  • Article

Acronyms and abbreviations can have an adverse effect on clarity, voice, andfindability. Although some acronyms are widely understood and preferred to thespelled-out term, others aren't well known or are familiar only to aspecific group of customers.

Don't create acronyms from product or feature names

Always spell out Microsoft product and feature names.

Only use acronyms that your audience is familiar with

The A–Z word list has guidelines for many common acronyms, and some acronyms are so widely used that they're in The American Heritage Dictionary.

If you have to use an acronym, also spell out the term for clarity

In general, include the acronym in parentheses following the spelled-outterm. On subsequent mentions in the same article, page, or screen, you canuse the acronym without spelling it out.

Some acronyms, like USB, FAQ, and URL, are more well known than the spelled-out term. Don't spell out the term if the acronym is listed in The American Heritage Dictionary or if the A–Z word listsays to use the acronym without spelling it out. If you're sure youraudience is familiar with an acronym, it's OK to use it without spellingit out.

Examples
Conversation as a platform (CaaP) has the potential to make booking a flight as easy as sending a text message. Developers are also looking to CaaP to make computing more accessible to users of all abilities.
Learn how to connect a USB device to your Microsoft Surface.

Don't introduce acronyms that are used just once

Ifan acronym will appear only once in your content, just spell out theterm. Don't introduce it in parentheses after the spelled-out version.

Exception It's OK to use both the spelled-out term and the acronym if both are needed for SEO, even if the acronym is used only once.

Be careful with acronyms in titles and headings

Avoid using an acronym for the first time in a title or heading, unless it's akeyword that you need to place in the title or heading for SEO. If thefirst use of the acronym is in a title or heading, introduce the acronym(in parentheses, following the spelled-out term) in the following bodytext.

Lowercase the spelled-out term

Lowercase all words in the spelled-out form of an acronym except for propernouns. The names of many protocols and specifications are consideredproper nouns and are capitalized when spelled out.

Examples
infrastructure as a service (IaaS)
dynamic-link library (DLL)
High-Definition Multimedia Interface (HDMI)

Use a or an, depending on pronunciation

Which article (a or an) you use depends on whether you pronounce the acronym like a word or pronounce each letter.

Examples
a DLL
an ISP
a URL
a SQL database

Add s to make an acronym plural

Form the plural of an acronym like you would any other noun. If the acronym stands for a singular noun, add a lowercase s to make it plural. If an acronym stands for a plural noun, don’t add an s.

Examples
three APIs
Microsoft Foundation Classes (MFC)

Avoid the possessive form

Unless an acronym refers to a person or an organization, avoid using the possessive form.

Examples
the IDE enhancements
the purpose of the FAQ
the CEO’s blog

Global tip In machine-translated content, be careful with acronyms that form common English words, like RAM. If the acronym appears outside of the parentheses and without the spelled-out version, it might be translated incorrectly.
