Simple English is a generic term for communication that emphasizes clarity, brevity, and avoiding unnecessarily complicated or technical terms. It encourages writers to create content that is clear and appropriate to the audience’s reading skills and knowledge.

Simple English improves the clarity of procedural technical writing, makes translation easier, and improves comprehension for people whose first language is not English.

Clear Linux* OS does not use controlled language, which restricts the writer’s vocabulary to a list of approved words. However, we do strongly recommend using the language principles described below.

Short sentences and paragraphs

Clear writing should average 15 to 20 words per sentence. This does not mean every sentence should be the same length. Vary your writing by mixing short sentences with longer ones, but stick to the basic principle of one main idea in a sentence, plus one additional point if needed.

Similarly, restrict your paragraph length to about six sentences. Remember the basic structure of a paragraph: Introduction, body, and conclusion. Both the introduction and the conclusion should be one sentence long. The body of a paragraph should never exceed four sentences. Here less is more.

Simple words

Choosing simple words increases reader comprehension and reduces ambiguity. Here are some guidelines on making good simple word choices:

  • Avoid jargon. Jargon is a type of language that is only understood by a particular group of people, such as an industry or a club. You can use jargon when writing for an audience who will understand, but avoid over using it, especially on the general public.
  • Be consistent. Use one term for each concept or action and use it consistently. Don’t use a different term for the same object or action when you refer to it subsequently.
  • Keep your style plain but avoid dullness. Avoid clichés, idioms, and metaphors. Many of these devices are not easily understood across different cultures and can lead to confusion.
  • Avoid “fancy” words and phrases. The goal is to get the information across, not to impress the reader with your vocabulary, so avoid bureaucratic, flowery or literary style. Here are some examples of “formal” words to avoid and preferred “informal” alternatives in parentheses:
  • commence (start, begin)
  • consequently (so)
  • in excess of (more than)
  • in the event of (if)
  • prior to (before)
  • should you wish (if you want)
  • utilize (use)
  • instance (example)

Strong verbs

The stronger and clearer you can make your verbs, the more directly you communicate information to your audience.

Keep these basic guidelines in mind as you check your verbs:

  • Use imperatives.
  • Use active voice not passive voice.
  • Avoid linking verbs; is, seems, becomes.
  • Convert weak verbs and nominalizations to strong verbs.
  • Be concise.
  • Avoid “there are” and “it is” constructions.


The examples in the following sections offer two versions of the same information. The incorrect version always comes first and is formatted in italics. The correct version always comes second and is formatted in bold.


Commands, officially called imperatives, are the fastest and most direct way of giving someone instructions. Imperatives are an extension of the second-person pronoun you. The word you is implied.

Be concise.


I would appreciate it if you would send it to me.

Send it to me.

Present Tense vs. Future Tense

Use simple present tense instead of future tense for most text. Future tense is acceptable for conditional statements, for example in a caution or a warning.

Action Verbs vs. Nominalizations

Avoid nominalizations, which are nouns formed from verbs. For example:

Verbs Nominalizations
complete completion
introduce introduction
provide provision
fail failure
arrange arrangement
install installation

The problem with nominalizations is that they are often used instead of the verbs they come from. Because they are merely the names of things, they sound as if nothing is actually happening in the sentence. Like passive verbs, too many of them make writing very dull and heavy-going.

Here are some examples.

We had a discussion about the matter.

We discussed the matter.

The blizzard will cause a stoppage of the trains.

The blizzard will stop the trains.

IT has completed the installation of the software.

IT has installed the software.

Infinitives vs. Participles

  • Avoid present participial forms and gerunds, words ending in -ing, unless they are part of a technical name.
  • Use infinitives instead of participials in this type of construction. For example:

There is no way of verifying this.

There is no way to verify this.

Active Voice vs. Passive Voice

Use active voice whenever possible to show clearly who or what is performing an action.

  • Active voice follows standard English word order: SUBJECT–VERB–OBJECT (optional). Modifiers come before or immediately following the terms they modify.
  • Passive voice reverses the order and weakens the verb: OBJECT–be VERB–by SUBJECT (optional).
  • Writing sentences in the passive voice, we often have to use the verb to be and sometimes the preposition “by”.


A mistake was made. (By whom?)

I made a mistake.

The sheriff was shot by me.

I shot the sheriff.

Version 2.0 was released in June.

We released version 2.0 in June.


Sometimes it is okay to use passive voice. For example, you may use passive voice to avoid gender-specific pronouns, to avoid blaming someone, or to address situations where the subject, who did the action, is unknown or irrelevant.

Noun phrases

Avoid long strings of nouns. Even native English speakers might have difficulty determining which term modifies one or another in long strings.

Similarly, avoid long noun phrases with multiple adjectives. Try to limit the number of modifiers in any noun phrase to two terms maximum.

Often the best way to split up these long noun strings is to separate them into digestible prepositional phrases. This tends to lengthen them but makes them much easier to understand.

Examples of some long noun phrases and possible rewording:

Power management mechanism integration policies

Integration policies for power management mechanisms

Signal integrity test deck requirements

Requirements for test desks that measure signal integrity

Building radon source location method

Method for locating the source of radon in buildings

Employee compensation level evaluation procedures

Procedures for evaluating an employee’s compensation level


First Person

We recommend using we or Clear Linux OS, if you want to sound more formal, to provide an agent, someone who does the action in a sentence, and avoid passive constructions such as “It is recommended....” For example:

5 MB is recommended.

We recommend 5 MB.

It is recommend that you set the value as low as possible.

We recommend setting the value as low as possible.

This setting has not been validated.

Intel has not validated this setting.

Second Person

Write directly to the reader and use the second-person pronoun “you” rather than “the user”. For example:

If the widget is to be compressed....

If you want to compress the widget...

If reduced costs are wanted...

If the user wants to reduce costs...

If you want to reduce costs...

Third Person

Third person pronouns tend to create subject-verb agreement errors because writers often introduce a gender-neutral third person plural they. Rewrite these sentences using a third person plural antecedent. Avoid third person singular pronouns, especially the gender-specific pronouns he and she, and, if necessary, rewrite these sentences using plurals to avoid a gender-specific references in gender-indeterminate situations.

The preferred hierarchy of third-person pronoun usage is:


If a user needs to update their account...

Do not use the third person plural for a singular subject.


If a user forgets her password...

Do not force the feminine pronoun set (she) unless there is a specific, approved feminine antecedent or there is some other very strong, circumstantial reason to do so.


If a user needs to update his account...

In traditional English usage, it is acceptable to use the masculine pronoun set (he) when the gender is neutral or indeterminate. This is often the rule in romance languages and other languages.


If users need to update their accounts...

Often the best solution is to use the plural form to avoid pronoun problems.
