Closed compounds and prefixes

In general, use the closed form of compound words and words with prefixes; that is, write them without a space or a hyphen. We've included some common examples of the closed form in the word list, such as dataset, metadata, and predefined, as well as our exceptions for well-established terms that commonly use a hyphen or a space, such as multi-region and style sheet. Additionally, in cases where the noun, verb, and adjective versions of a word are treated differently, we explicitly note the differences.

As always, it's fine to deviate from this guidance if that serves your users better. For example, if you determine that the hyphenated version of a term in your domain is more appropriate for your users, it's fine to use that instead. We acknowledge that sometimes there are competing forms of the same word in wide use, especially as new terms emerge, and you might have good reasons for deviating from our guidance. Use the same term consistently throughout your document.

Word list

Some word list entries include guidance to avoid or don't use a term. Apply this guidance as follows:

  • Avoid: A recommendation to avoid using the term when possible. The term might be ambiguous or obscure, so we provide alternative term suggestions or suggest that you use a more specific term. However, you can use the term if needed.
  • Don't use: In all cases, we prefer to not use the term. The term might be particularly ambiguous or it might have an offensive or non-inclusive association. If such a term appears in code, we recommend that you replace or write around the term.

  • For the noun whitelist, consider using a replacement such as allowlist, trustlist, or safelist.
  • For the noun graylist (greylist), consider using a replacement such as provisional list.
In all of these cases, consider that there might not actually be a list involved. When replacing problematic terms, be sure to be technically accurate for the specific context.For the verb forms of these words, a simple word-for-word replacement is typically not the best solution. Instead, replace verbs such as blacklisted with phrases that accurately convey the relevant action. For example:Recommended: To deny requests from an IP address, add it to the dos.yaml file.Not recommended: To denylist an IP address, add it to the dos.yaml file.Don't use: To blacklist an IP address, add it to the dos.yaml file.If the command or code that you're documenting uses one of these words, then use these words only in direct reference to the code items (formatted as code), and make it clear what you're referring to.Recommended: Add a user to the allowlist (whitelist) by entering the following: whitelist adduser EMAIL_ADDRESS.Not recommended: Add a user to the whitelist by entering the following: whitelist adduser EMAIL_ADDRESS.For more information, see the inclusive documentation page.blacklisted, black listed, black-listedSee blacklist.blacklisting, black listing, black-listingDon't use.

Instead, use tap.click hereDon't use. For details and alternatives, see Link text.clickthrough (noun), click through (verb)clientIn REST and RPC API documentation, client is short for client app—that is, the app that the developer is writing.

In Android documentation, don't use earlier for a range of version numbers. Instead, use lower.When referring to a position in a document, use earlier or preceding, not higher.easy, easilyWhat might be easy for you might not be easy for others.

Too many people mix up e.g. and i.e.egressWhen referring to the networking term, use lowercase.eitherUsage note 1: When using either, use parallel syntax. It's fine to write Do either option 1 or option 2 or Either do option 1 or do option 2, but don't write Either do option 1 or option 2.Usage note 2: We recommend using either only for a choice between two things, not for a choice among multiple things; however, this is a weak recommendation rather than a firm rule. Writing either A or B or C will annoy and distract some readers, but if it's the best phrasing for your situation, then use it.elementIn HTML and XML, a tag is a component of an element that indicates the start or end of the element. (For example, the <i> start tag indicates the beginning of the <i>example</i> element.) In general, don't use the term tag to refer to an entire element.email; not e-mail or Email or E-mailAs of mid-2017, Merriam-Webster dictionaries still prefer e-mail to email.

If you are referring to a system or component being slowed, use the word slowed.retriable, triableDon't use retriable or triable, unless a code item uses that spelling. Outside of code font, write around the term.retryable, tryableWhere possible, write around retryable and tryable. For example, write out can be tried again or you can try it again.reviewIf you mean "read, potentially for the first time," then use read instead of review. If you mean "read critically, commenting on problems" (as in code review), then review is fine; the usage to avoid is phrasing like If you've never heard of OAuth, then review the OAuth documentation.RFCWhen referencing an RFC specification, use a space between RFC and the number (for example, RFC 2318).roll outDon't use to mean a sudden or instantaneous launch.

SaaSWrite out on first mention: software as a service (SaaS).saneDon't use. Instead use a word like valid or sensible.sanity checkDon't use. Instead, use a term like quick check, confidence check, preliminary check or coherence check.SAPPronounced as the individual letters S, A, P, so write an SAP system, not a SAP system.scale Don't use scale alone to say that something is large or increasing. Include supporting words to indicate magnitude or direction of change in magnitude, whether scaling up or down, such as when you change a machine type to add or remove CPUs or RAM, or scaling out or in, such as adding or removing instances from a group.Recommended: The system performs better at a larger scale.Not recommended: The system performs better at scale.Recommended: The system scales up quickly, but it scales down more slowly.Not recommended: The system scales quickly.screenshot (noun); not screen shot or screensnapDon't use as a verb; instead, use take a screenshot.scrollOK to use scroll as a verb, but if possible, instead use a term that isn't specific to implementation.

Use they and their for the general singular pronoun.sherpaIf possible, use a more precise term. For example, if you mean guide, use that term.shift leftIn general, avoid using this term to mean moving something earlier in time. Instead, use a less figurative phrase, such as shift earlier or move to an earlier phase. This figurative term relies on the non-universal assumption that the natural flow is from left to right.It's OK to use shift left and shift right in the context of binary multiplication and division.should, should beGenerally avoid.Because should is ambiguous by definition, it can be problematic. For example, if you're telling the reader what to do, should implies that the action is recommended but optional, leaving the reader unsure about what to do.Clarify what you mean. Determine if an action is required versus optional, an outcome is expected versus possible, or a state is actual versus recommended.
  • An action is required. Use must, or rephrase the sentence so that it is a clear imperative instruction such as Do the following before you continue.
  • An action is recommended. Use We recommend... or Google recommends…. You can use should if a recommended action is generally recognized—for example, You should use a strong password…, or, You should follow the principle of least privilege....
  • An action is optional. Use can. For example, You can also use approach B to solve the same problem.
  • An outcome is expected. Describe the outcome in terms of what is expected. For example: The process returns 10 items.
  • An outcome is possible. Use might or can. For example, The process can take about 30 minutes.
  • A state is actual. When you're describing the state of something, such as the value of a variable, avoid writing The value should be true. Instead, clarify which of the following you mean:
    • You must set the value to true.
    • The server sets the value to true.
    • If the value is false, follow these steps to change it to true.

Use the hyphenated version as part of single sign-on.sign-out (noun or adjective), sign out (verb); not log out or signout simple, simplyWhat might be simple for you might not be simple for others. Try eliminating this word from the sentence because usually the same meaning can be conveyed without it.sinceIf you mean because, then use because instead of since. Since is ambiguous; it can refer to the passage of time. Because refers to causation or the reason for something.single most; not singlemostsingle pane of glassAvoid. This term is used to favorably compare a centralized control and monitoring interface against the alternative of several disparate interfaces. It can almost always be replaced by single interface or unified interface.single sign-on (noun or adjective)slaveDon't use. Instead, use alternative terms appropriate to your domain, such as worker or replica. If you are replacing the terms master and slave together, then consider such combinations as primary/secondary, primary/replica, original/replica, controller/worker, initiator/responder, mixer/leaf, aggregator/collector, publisher/subscriber, leader/follower, and active/standby. If the command or code that you're documenting uses the literal word slave, then use this word only in direct reference to the code item (formatted as code), make it clear what you're referring to, and use the new term thereafter. For example, Invoke the secondary (slave) process directly when debugging issues between the primary and secondary processes.See master.slice and diceDon't use the phrase slice and dice. Instead, use specific terms appropriate to the task at hand. Some possible options include: segment data for analysis, break information into smaller parts.smartphone, smart phoneDon't use. Instead, use mobile phone or phone. If you're talking about more than phones, then use mobile device. It's OK to use phone (without mobile) when the context is clear.soonAvoid in timeless documentation because this word can become outdated. The word can also prematurely disclose product or feature strategy or inappropriately imply that a product or feature might change.See also eventually and future.Recommended: This setting is optional.Not recommended: This setting is optional for existing applications but will soon be required for all applications.For more information, see Timeless documentation.source network address translation (SNAT)Also okay to use source NAT after first mention.
