Grammar and mechanics
Our UX writing style follows our in-product voice principles.
These guidelines apply to text in U.S. English, our source language for writing in-product content. Defer to component-level style guidance when needed, and keep in mind that in-product language is internationalized according to specific locale standards and style.
Table of contents#
AP style#
We use Associated Press (AP) style for in-product UX writing, with any exceptions noted on this page.
Active and passive voice#
Use active voice in most cases and use passive voice sparingly.
- With active voice, sentences are simpler, shorter, clearer, and more conversational.
- With passive voice, you can soften and provide distance in select situations (e.g., notification of a disabled account).
Active voice#
In an active sentence, it's clear who's doing what. The actor is the subject, and the subject of the sentence is doing something.
Passive voice#
At times, active voice can come across too harshly. In these cases, use passive voice. This separates the actor from the action enough to soften a sentence.
In a passive sentence, action is being taken upon the subject.
Avoid passive voice by reframing the focus#
You can usually reframe a message to focus on the object, or on the actions someone could take, as another way to avoid passive voice.
Contractions#
Use contractions to sound more conversational and natural.
Common contractions#
Use commonly understood contractions to keep sentences from feeling out-of-touch, robotic, or overly formal.
Some common contractions:
- What's
- We'll
- You'll
- You're
- You've
- We're
- They're
- Doesn't
- Didn't
- Isn't
- Aren't
- Can't
Contraction considerations#
- Avoid contracting nouns with is, does, has, or was. This might make it look like the noun is possessive.
- Don’t use uncommon or old-fashioned contractions (e.g., would’ve or tweren't).
- Don’t use colloquial contractions (e.g., ain't, y'all, yinz).
- Be mindful of how many contractions you use in a sentence. Too many contractions can make things difficult to read.
- Avoid using contractions when dealing with legal concerns, payment processing, and account security. Casual isn’t always the best style when handling sensitive information.
Verb tenses#
In general, use simple verb tenses: past, present, and future. Simple tenses are used to describe actions without specifically stating whether the actions are completed (perfect tenses) or ongoing (progressive tenses).
Use simple future tense to describe the result of an action or instant process that’s happening now, or to describe something that will occur in the actual future (i.e., not at the time someone encounters the message).
| Tense | Simple | Not simple |
|---|---|---|
| Past | You updated this app to version 13.1. You entered an incorrect password. | You’re updating this app to version 13.1. You’ve entered an incorrect password. |
| Present | Here are all of the spaces you can access. You can't undo this action. | Here are all of the spaces you’ve accessed. You’re not undoing this action. |
| Future | If you turn off snapping, you won’t be able to use the relative spacing feature. Your credit card will be charged at the end of your trial. | If you turn off snapping, you won’t be using the relative spacing feature. Your credit card will have been charged at the end of your trial. |
Why we use simple verb tenses#
There are a number of reasons why we use simple verb tenses for in-product writing:
- They use fewer words and are more concise.
- They can make content easier to scan and faster to read. Fewer words and simpler phrases mean better readability.
- According to the latest U.S. Census, more than 20% of people living in the U.S. speak a language other than English at home. For more people, simple verb tenses are easier to understand.
- Present tense improves readability scores.
What's not simple tense#
If any of the following comes before the verb in a sentence, it’s not simple tense:
- Was/wasn’t, were, weren’t
- Has/hasn’t, have/haven’t
- Is/isn’t, are/aren’t
- Be
If the verb in a sentence ends in “-ing,” it’s not simple tense.
Capitalization#
Sentence case#
Use sentence case for all aspects of designing Adobe product experiences, including titles and UI elements (e.g., tooltips, tabs, menu items).
Writing in sentence case has been proven to be easier for users to read and comprehend, it sounds more friendly and less formal, and it helps better identify proper nouns and branded terms that need to be capitalized.
When to use sentence case:
- Only capitalize the first word in a phrase, title, or UI reference (e.g., Adjust borders tool)
- Always capitalize proper nouns and branded terms (e.g., Adobe Help Center)
- Capitalize acronyms (e.g., XD, AEM)
Title case#
Use title case only when it clarifies that we’re speaking about a specific, official entity (such as a title or name). Title case is often a marker of formality in English, and overuse can cause users stress by implying formality or officialness where it doesn’t exist.
All caps#
Use all caps sparingly.
When to use all caps:
- Acronyms, such as accepted product names on second attribution (e.g., Adobe Experience Manager (AEM))
- Names of file extensions (e.g., TIF, ZIP, or PSD files)
All caps should never be used to emphasize a point.
Pronouns#
Referring to the user#
In UX content, we want to talk about what’s happening rather than who or what is making something happen.
We avoid speaking as our users. In nearly all situations, we aim to be conversational and talk to the user — not as them. Any exceptions depend on situational needs for sensitivity and clarity.
Second person#
Most of the time, use second person (you, your, you’re) to address users and services.
First person#
Use first person (me, I, my) only in these situations:
- Someone responds to the interface or answers a question they've been asked directly
- When additional sensitivity is necessary, or to indicate privacy
- When there's a legal need to use first person to ask for consent (e.g., “I agree to these terms and conditions”)
On rare occasions, it can be appropriate to use we or us to mean “Adobe”:
- "We're sorry" (for a critical error)
- "Help us improve this feature" (requesting feedback)
Singular they#
In most situations, Adobe doesn't need to know or assume the gender of our users. So when we refer to users, we use singular they.
We don’t use “he/she” or “(s)he” — those are clunky and they exclude users who identify outside of the male/female binary.
Use any of these variants of they in their proper grammatical contexts:
- They
- Them
- Their
- Theirs
- Themselves
- Themself
Punctuation#
Punctuation marks are an essential part of language, and they extend beyond running text. They appear in code, mathematical equations, keyboard shortcuts, file names, and more. When there are established conventions for such contexts, punctuation marks should follow those conventions.
In general, don’t use punctuation marks in place of words (e.g., "&" instead of "and" or "@" instead of "at"). And, don’t use them as design elements, or for anything purely stylistic in purpose.
For punctuation within blocks of code, use the Code typography component to differentiate the code from other written text.
Ampersand#
Don’t use ampersands (&) in UI copy. Instead, spell out the word “and.”
Using the word “and” is more inclusive, localizable, and readable:
- It’s more widely known and understood for people who are non-fluent English speakers
- It translates more easily into many languages
- Spelled-out words require less mental and cognitive effort to read
- Ampersands bring attention to the conjunction in a phrase which is the least important part of the sentence
- The ampersand symbol can be distracting, since it’s taller than many letters and is an unusual shape
Apostrophe#
Don’t use apostrophes (') in place of quotation marks.
When pluralizing singular and plural words, add apostrophe-"s" when there’s no "s" at the end. For plural nouns that end with "s," add only an apostrophe.
For any other specifics on possessive apostrophes, refer to the AP style handbook.
Asterisk#
Use asterisks ( * ) or "(required)" to establish form fields as required. Don’t use asterisks to denote anything as optional.
Make sure to use the Spectrum asterisk icon that comes built in with the design components — not the text form of an asterisk within the label string.
Don’t use asterisks in running text or labels when parentheses or a tooltip would suffice.
At sign#
Don’t use the at sign (@) in place of the word "at."
Brackets#
Don’t use brackets ([] {}) in UI copy or running sentences. Instead, use parentheses ( ( ) ).
![Key example of using parentheses instead of brackets. Incorrect usage. Downloading… [1 of 2], with brackets instead of parentheses surrounding the “1 of 2” count.](/static/images1x/grammar-and-mechanics_brackets_dont@2x_1Wu32mtJdP3D7jRUSJfRTc_1611634931943.png)
Colon#
Try to simplify a complex sentence into multiple sentences first, but if you can’t, try a colon (:).
Colons are helpful when introducing lists of items or steps in a workflow. The lists and steps should be introduced on new lines. They’re also useful for high-level headlines or marketing-sounding UI content.
Don’t use a colon at the end of a label for a form field. The design component should already communicate the relationship between the label and the input.
Comma#
When listing things, use the serial comma (also known as the Oxford comma). This means providing a comma before the word “and” when listing multiple items in a sentence.
If you’re having to use a lot of commas in a sentence, consider whether you can split the sentence up with periods or em dashes.
Ellipsis#
In general, use ellipses (…) when truncating text in small spaces.
Use an ellipsis at the end of the text to communicate the progress of something that is in process, such as a waiting or loading state.
Don’t use an ellipsis in a call-to-action on a button to communicate that there’s a page or action beyond the button.
For hint text, if an action starts a process, use an ellipsis at the end of the text (e.g., “Add names or email addresses…”).
For menu items, adding an ellipsis at the end of the menu item will depend on if your product is using a native (OS-level) pattern or not. For a native menu that your product is adding to, defer to the native pattern. For a menu that doesn’t follow a native pattern, only prompt text (ghost text) should use an ellipsis. A menu item does not need an ellipsis, even if the item is an action.
If you need to directly refer to a UI element whose name ends with an ellipsis (e.g., “Find…“) in running text, drop the ellipsis: “Use Find to search the database.”
When using an ellipsis on a More menu, don’t use it as part of a string, and make sure to use the appropriate icon.
Emoji#
Don’t use emoji in any interface language.
Emoji often convey tones that may be inappropriate in certain contexts. They’re also difficult to localize, and tend to diminish readability and comprehension.
Equals sign#
Don’t use an equals sign (=) in place of the word "equals," and don’t use this as shorthand for "meaning," "means,” or "is."
Exclamation mark#
Don’t use exclamation marks (!) since they are difficult to localize and easy to overuse.
Greater than and less than#
When communicating navigation, such as in breadcrumbs, use the "chevron" icon built into the component, not the greater than symbol.
Don’t use the greater than and less than symbols to communicate steps in a flow — use bulleted or numbered lists instead.
Don’t use these symbols to replace the words "greater than" or "less than." And don’t use them to accent or decorate a word.
Hyphen and dash#
Use em dashes (—) to separate distinct but related thoughts. Include spaces before and after the em dash.
Use en dashes (–) for number ranges and lengths of time, with no spaces before or after the en dash. Don’t use them when paired with the words “from” or “between.”
When needing to show gaps in data in a table, use an en dash to represent null, unavailable, or inapplicable values.
Use hyphens (-) between words, and with no spaces before or after the hyphen.
Minus sign#
Don’t use the minus sign (-) in place of the word “minus,” “without,” “less,” “negative,” or other words related to subtraction.
Parentheses#
Use parentheses ( ( ) ) to provide supplementary context.
Don’t use parentheses in simple tooltips. In rich tooltips, they can indicate keyboard shortcuts. Don’t use brackets in place of parentheses.
![Key example of using parentheses. Two examples of incorrect usage, with parentheses not needed or brackets used instead of parentheses. Cloud documents are saved online to Adobe's cloud (collaboration and other features are on the way). Clone Stamp tool [keyboard shortcut, S].](/static/images1x/grammar-and-mechanics_parenthesis_dont@2x_iV6FYMmqUcLWgbbqFmX8v_1611634953493.png)
Period#
In general, if your text is a full sentence, add a period to the end. If it's a short, direct phrase — either standalone, or within a UI component like a toast or alert banner — don't add a period.
In the majority of cases, don’t use periods (.) or any other punctuation on the end of bulleted or numbered lists. If one list item is a complete sentence, then it would end with a period (or question mark). In this case, use periods at the end of all items.
Don’t use periods in headers or buttons.
Plus sign#
Don’t use plus signs (+) in place of the word "and," bullet points, or as any other design elements.
Don’t use plus signs when indicating there is more of something available.
Question mark#
When writing titles, questions marks (?) are the only acceptable punctuation mark to include.
Avoid using question marks to ask rhetorical questions.
Quotation mark#
In UI copy, only use quotation marks (“”) when quoting someone’s words or when referring to a file or asset name. Always use smart quotation marks (also called “curly” or “directional”), except when showing code.
Smart quotation marks are easier to read because they better match the other characters in a typeface. Straight quotes may also be confused with prime symbols, which are used for measurements.
Don’t use quotation marks when directly referring to interface elements. View the Typography page for guidance on using bold text to do so.
Semicolon#
Don’t use semicolons (;). If you need a break in a sentence, use periods, commas, or occasionally em dashes.
While semicolons are useful for connecting two related thoughts, they add a formal and academic tone to text and have shown to negatively affect user comprehension in UX writing.
Slash#
Don’t use backward slashes, and don’t use a forward slash ( / ) to combine words or ideas. This comes across as noncommittal, and affects comprehension and clarity. Instead, use the words “and” or “or.” Don’t use “and/or.”
Vertical bar#
Don’t use the vertical bar (|) in running text. Avoid using it to divide information in places other than webpage titles tags and footer info. It shouldn’t be used for purely stylistic or decorative purposes when blank space between items is sufficient.
When you use the vertical bar, use an icon and not its text form. Additionally, make sure you change its name in JAWS to “Pause” for proper accessibility.
Abbreviations#
Use abbreviations consistently throughout your experience to help with predictability and usability. When writing string descriptions or alt text, be sure to write the full word so that the content can be properly localized and so screenreaders will read the actual word instead of spelling out the abbreviation.
Amounts#
Use K for thousands, M for millions, B for billions, capitalized, no periods. Include a space between the number and the unit of measurement (e.g., "71 M records found").
Measurements and dimensions#
For full sentences where measurements or other numbers are present, use AP style and spell out the unit of measurement (e.g., 2 points, 2 picas, 2 pixels, 2 megabytes).
Similarly, use AP style when abbreviating measurements or time. Make sure there’s a space between the number and the unit of measurement (e.g., 2 pt, 2 MB, 2 min, 2 hr).
Months#
Use Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec (no periods).
Days#
Use Sun, Mon, Tue, Wed, Thu, Fri, Sat (no periods).
Time#
Use sec, min, hr as singular, no periods, no comma, and with a space in between the number and the unit of time (e.g., 1 hr 21 min).
Use lowercase am and pm indicators without a preceding space, unless you’re describing 24-hour time (e.g., 17:15).
Numbers#
Currency#
Use the numerical form of $1.00 when formality is needed, or when the number is dynamic and might include cents.
Use the number form of $1 when you need a more casual, neutral tone or if there is a space constraint and you can round off to the nearest dollar.
Use the international abbreviation for the currency when you need to disambiguate types of currency (e.g., "$100 USD equals $138.21 SGD").
Large numbers#
Use a comma to offset groups of three digits, for readability:
- 10
- 100
- 1,000
- 10,000
- 100,000
- 1,000,000
But for the best readability, when citing large, round numbers, spell out the word:
- 4 thousand
- 81 million
- 2.5 billion
Numerals#
In running text, write out the words zero through nine, then start using the number for 10 and higher. When telling time, presenting a series or range, or providing a timestamp, use the number forms: 0 through 9.
You can adjust how you format numerals if you feel it’s appropriate for your situation. Using a number adds more emphasis than spelling out the word. For example, if you were to say “Compare two files and see the changes,” the emphasis is on the comparison, not on the number of files. "Read all eight comments" focuses on the availability of comments; "Read all 8 comments" focuses on the number of comments.
If you’re mentioning currency or time alongside other types of numbers, spell out the number to make the currency or time more prominent.
Percentages#
Use the percent symbol (%) instead of spelling out the word "percent."
Dates and time#
Dates#
Date formatting is contextual, and it will depend on your product and use case. Different kinds of date formatting can be used for standalone strings in running text or for strings in more data-rich views.
Some experiences might require the full format, where others might require something more compact:
- Full: Monday, August 21, 2017 at 3:07pm
- Compact: Mon, Aug 21, 2017, 3:07pm
Additionally, dates are often localized. For example, in Europe and the U.K., the previous date example would be written:
- Full: Monday, 21 August at 15:07
- Compact: Mon, 21 Aug, 15:07
For U.S. English, you can also format dates as MM-DD-YYYY, using the numeral for the month instead of the word. Use a 2-digit format (including a 0, even with single digit months and days). The 2-digit format also helps make it easier to parse and compare multiple dates, especially in tables or lists:
- 02/24/2000
- 04/01/2015
Work with a localization expert to localize dates and times for your product’s specific cases.
Learn more about the formatting for abbreviating dates (months and days) in the Abbreviations section.
Time#
- Do not use :00 with whole numbers
- When presenting a range of time, use an en dash without spaces in between, and do not include am or pm on the first time if it’s the same as the last
- When translating to 24-hour time, do not include am and pm (e.g., 17:15)
Learn more about the formatting for abbreviating time (hours, minutes, seconds, and am and pm indicators) in the Abbreviations section.
Timestamps#
For a timestamp in a video editor where precision is needed, go by hour, then minute, then second, following this formula: HH:MM:SS.
In a tutorial playlist, for example, less detail is needed. If the video is less than an hour long, omit the hours.
Time zones#
Avoid time zones unless absolutely necessary — if possible, dynamically convert to the user’s time zone.
- If the time zone is absolute, use the common name, like Pacific Time, or India Standard Time. Don’t use UTC formulas.
- If space is constrained, use a time zone's acronym (e.g., PST, EST), but make sure you provide extra context to your localization team if doing so.
- For relative time and clarity, say “in your time zone.”
Lists#
Use lists to break down complex ideas and make them more readable and scannable. You can also use them to make parallel choices easy to compare.
- Use bulleted (unordered) lists to present two or more concepts of equal weight
- Use numbered (ordered) lists to present a series of sequential steps
Introductory phrases#
Use an introductory phrase with a colon to lead into the list, and write each list item so it works with that phrase.
Be consistent and use parallel construction#
Phrase your list items to be consistent with each other as much as possible. This helps with comprehension and readability.
Some things to keep in mind when writing lists:
- Capitalize the first letter of each list item.
- Generally, don’t use terminal punctuation in list items, unless it’s a complete sentence or sentences.
- If the list includes action items (as in a series of instructions), the entire list should follow the same format, with the verb first. If it’s a list of nouns, all items on the list should include nouns.
Capitalize each list item#
Capitalize the first letter of each list item and use sentence case.
