					Simplified English
What Is Simplified English? Simplified English (SE) was developed so that documents written in English could be
understood by people who speak little English. To make the documents easier to understand, Simplified English
uses a limited vocabulary and a set of writing rules. The writer can only use words on the approved list and
technical terms (words common to tile field). Each word on the list has only one approved definition. For
example, “about” is used for “concerned with.” It cannot be used for “around” or “approximately.” Verb tenses
are also restricted. The rules listed below were developed for the AECMA. The principles for simplified English
can be used even if AECMA rules are not strictly followed. Many of the words on the AECMA approved list
would not be needed for Church products. Many words needed for Church products are not on the AECMA
approved list.

Example of Simplified English
Original paragraph:
    Place the water heater in a clean, dry location as near as practical to the area of greatest heated water
   demand. Long uninsulated hot water lines can waste energy and water. Clearance for accessibility to per-
   mit inspection and servicing such as removing heating elements or checking controls must be provided.

Same paragraph in Simplified English:
   Put the water heater in a clean, dry location near the area where you use the most hot water. If the hot
   water lines are long and they do not have insulation, you will use too much energy and water. Make sure
   you have access to the heating elements and the controls for inspection and servicing.

(The above example is from “Learning to Use Simplified English: A Preliminary Study,” by Margaret Thomas,
Gloria Jaffe, J. Peter Kincaid, and Yvette Stees, Technical Communication, First Quarter 1992, pg 70)

AECMA Simplified English Rules
Words
1. Use only approved words.
2. Use approved words only as the part of speech given. (example: close is a verb [and not an adverb].
   Write: Do not go near the landing gear if... NOT: Do not go close to the landing gear if...)
3. Keep the approved meaning; do not add any other meaning. (example: Follow means “to come after.” It
   does not mean “to do what the rules tell you.” Write: Obey the safety instructions. NOT: Follow the
   safety instructions.
Technical Names
4. You can use words that are “Technical Names.” (These words are not part of the attached list of words.)
   A word, symbol, or term is a “technical name” if it is in one of these categories: names of: official parts,
   locations on aircraft, tools or equipment, materials, support facilities, circuits or systems, persons,
   groups, or bodies, technical records, standards, regulations, and the following categories of terms: math-
   ematical, scientific, engineering, navigational and flying, measurement or dial markings, number, parts
   of the body, common personal effects, medical, documents and manuals, names, headings, & topics used
      in specifications, environmental conditions, colors, damage terms. (The categories are from the aero-
      space industry. Another list would be needed for Family History.)
5.    Use a technical name only as a noun or an adjective, not as a verb.
6.    Use the official name (shortened if necessary) as much as possible.
7.    Do not use different technical names for the same thing.
8.    If you have a choice, use the shortest and simplest names.
Verbs
9. You can use the verb in these tenses: the infinitive, the present tense, the past tense, the simple future
    tense, and the past participle (as an adjective). (example: To adjust; It adjusts; It adjusted; It will adjust. It
    is adjusted.)
10. Do not use forms of the verb not shown in the “Approved Words” (such as verbs in the “-ing”
11. Use the past participle only as an adjective: either with a noun or after the verbs “to be, to become.”
    (example: Connect the disconnected wires again. The wires are disconnected. The wires become discon-
    nected.)
12. participle with a helping verb to make a complex verb. (example: Write:...is adjusted. NOT:...has
    adjusted. Write:...you can adjust NOT: can be adjusted. Write: Adjust the... NOT:...must be adjusted)
13. You can use verbs that are “Manufacturing Processes.” A manufacturing process does the following to
    material: removes, adds, attaches. changes the mechanical strength, structure or physical properties,
    changes the surface finish, changes the shape. (The categories are from the aerospace industry. Another
    list would be needed for Family History.)
14. Use the active voice as follows:
     • Procedures: use only the active voice
     • Description and Operation: use the active voice as much as possible; use the passive voice only when
       absolutely necessary.
15. To change a passive construction to the active:
     • Change the subject at the beginning of the sentence.
     • Change an infinitive verb to an active verb.
     • Change the verb to the commanding form.
     • Use the personal pronouns “we, you.”
16. Let the verb show the action. (example: Write: the ohmmeter shows... NOT: The meter gives an indica-
    tion of...) Sometimes it is not possible to follow this advice in SE, because of the limited choice of
    words. For example, in SE you must write: “Do the leak test,” instead of “Test for leaks.” This is because
    “test” is only used as a noun.
17. 17. Do not omit a verb (or nouns) to make your sentences shorter. (example: Write: Set the rotary switch
    to INPUT. NOT: Rotary switch to INPUT.)
Abstraction
18. Repeating words. In SE, you will often have to repeat the same word many times in one text. This is
    because the number of words is limited, and their meanings are strictly defined. This repeating of words
    helps the reader to understand the text. He becomes familiar with patterns of words and their meanings.
    You must not confuse your reader by using different words to describe the same thing. Once you have
    chosen the words to describe something, continue to use these same words.
19. Make your instructions as specific as possible. (example: Write: If you increase the temperature it will
    decrease the curing time. NOT: Different temperatures will change the curing time.)
The Grouping of Words
Remember that your reader may only have a poor knowledge of English. He will read/translate a text bit by
bit, and will not understand a phrase if the relationship between the words is not clear.
20. If it is possible, you must put an “article” (the, a, an) or a “demonstrative adjective” (this, that, these,
     those) before a noun. (examples: Write: Stop the start procedure if... NOT: Stop start procedure if. Write:
  • Hold the main gear doors up.
  • Set the alternate control lever to DOWN.
  • Set the alternate control lever to NORMAL.
Not: Support main gear doors, position alternate control lever fully DOWN and return to NORMAL.)
21. Break up noun clusters that have more than three nouns. Such “noun” clusters are almost impossible to
    read for some non English readers. This is probably because these readers begin with the first noun as
    they do in their own language. But the noun that the reader needs is at the end of the “noun cluster.”
    (example: Write: The temperature of the exhaust gas from the engine. NOT: The engine exhaust gas tem-
    perature...)
If an official technical name is a noun cluster (example: the main gear inboard door retraction winch handle),
there are three ways to help your reader:
22. Use hyphens to show the relationship between the words. (example: The main-gear inboard-door retrac-
    tion-winch handle.)
23. Explain the name. (example: [the handle that is used to operate the winch that retracts the inboard door
    of the main gear
24. Explain to the reader that you will use a shorter name. (example:...retraction-winch-handle In this chap-
    ter. the handle is referred to as the “winch handle.”)
Length of Sentences
25. Keep sentences as short as possible.
26. The maximum length of sentences is 20 words.
27. An average of one sentence in ten can be up to 25 words long.
28. When you count words for sentence length, the colon and the dash count as a full stop (period).
29. When you count words for sentence length, each word in a hyphenated group counts as a separate word
    unless it is a prefix.
30. When you count words for sentence length, text inside parentheses counts as a new sentence.
31. Keep to one topic or one instruction per sentence.
32. Write more than one instruction per sentence only when two actions have to be done at the same time.
    (example: Hold the switch to “TEST” and make sure the light comes on.)
33. Use connecting words to join separate sentences. (Write short sentences that are logically connected by
    connecting words. Connecting words will help to show the relationship between the different topics in
    the separate sentences. Such connecting words are: “Thus, also, so but, and, then, now.” You may start a
    sentence with “but” or “and.” Just make sure that you do not start too many sentences with “and,” as this
    will weaken your text.)
34. Use a tabular layouts (vertical layouts) for complex texts. (example: When the landing gear retracts,
    these movements occur:
  • The door-operating bar on the leg touches and turns the latch.
  • This causes the roller to move out of the slot.
  • The second roller holds the door-operating bar.)
35. In descriptive writing, try to vary sentence lengths and constructions to keep the text interesting.
36. In an instruction, write the verb in the imperative form (as though “must” were written in front of it).
37. In an instruction, the subject of the verb is implied as “you,” but this is not necessarily written into the
    sentence. (example: Remove the bolts = (You must) remove the bolts.)
Paragraphs
38. Use paragraphs to show your reader the logic of the text.
39. Each paragraph must have only one topic. The paragraph must deal with that topic in a logical manner
    and must make the relationship between sequences of information clear to the reader. You must not put
    unrelated pieces of information into the same paragraph. If one paragraph is not sufficient for all the nec-
    essary information, divide the subject matter and deal with each separate aspect in its own paragraph.
40. Always start the paragraph with the topic sentence. By reading only the topic sentences, the reader
    should be able to understand the broad outline of your text. If the reader is looking for some specific
    information, the topic sentence should be able to help him decide which paragraph he needs.
41. Use connecting words to make the relationship between sentences and paragraphs clear.
42. The maximum length of a paragraph is 6 sentences.
43. Do not use one-sentence paragraphs more than once in every 10 paragraphs.
44. Present new and complex data slowly.
Punctuation
We use punctuation marks to show how parts of the text are related to each other. They help to make your
text more readable and to make the meaning clear. Punctuation marks must not be scattered according to
“taste.”
45. If you start an instruction with a descriptive statement (dependent clause), you must separate that state-
    ment from the rest of the instruction with a comma. (example: When the light comes on, set the switch to
    NORMAL.)
46. Use hyphens as a joining signal. When we wrote these rules, we kept in mind the main objective: that
    readers should never have to reread a text to work out which words were intended to be read together.)
    Rules for when to use hyphens:
  • Two word terms used together. Low-altitude flight, quick-acting clamp, high-pressure chamber
  • Two word fractions or numbers. forty-seven, one-half
  • Adjectives that consist of three or more words. three-to-one ratio, soap-and-water solution
  • Terms that consist of a capital letter or number and a noun. L-shaped bracket, 3-prong connector
  • Compound verbs that consist of a verb plus a noun. die-cast. arc-weld
  • Terms in which the prefix ends with a vowel and the root word begins with a vowel. de-ice, de-energize,
    pre-amplifier
  • Terms in which two one-syllable words are written together but the first is not a simple modifier of the
    second by-pass, run-on torque
47. Use parentheses to set off text that is not part of the main statement but is important enough to be indi-
    cated or to mark text for which separation by commas is insufficient.
48. Use the colons and dashes only in tabular layouts (vertical layouts) with standard punctuation as follows:
  • Each breakout starts with an upper case letter
  • Do not put a period at the end of each breakout, but only at the end of the last breakout to show the end Of
    the sentence
  • If the sequence of the breakouts is important, number them in agreement with your in-house specifications.

Warnings and Cautions
Warnings and cautions tell a technician that parts of the procedures can be dangerous. A warning tells him
that injury or death is possible if he does not follow the instructions. A caution tells the technician that dam-
age to equipment is possible.
  • Start a warning or a caution with a simple and clear command.
  • Add a brief explanation to a warning or a caution to give a clear idea of the possible risk.
example: WARNING: DO NOT GET ANY ENGINE OIL ON YOUR SKIN FOR LONG PERIODS. THE
OIL IS POISONOUS. IT CAN GO THROUGH YOUR SKIN AND INTO YOUR BODY.

How to make a Simplified English Vocabulary
The information below came from the attached article, “Developing a Simplified English Vocabulary” by
D.A.T. Peterson, Technical Communication, Second Quarter, 1990, pp 130-133.
To create a simplified English vocabulary for his field, D.A.T. Peterson analyzed the text of four technical
manuals and extracted the core vocabulary. The four manuals covered different topics. A word processing
program was used for analysis. The program provided an automatic count of how many times each word was
used in the document.
To develop the core vocabulary, Mr. Peterson did the following:
1. Deleted numerals, abbreviations, and punctuation.
2. Arranged remaining text in alphabetical order.
3. Merged and sorted the four lists.
4. Deleted words for items, actions, conditions, and processes (technical words). The remaining words
   became the initial core vocabulary.
5. Compared the initial core vocabulary to Charles K. Ogden's 850-word Basic English vocabulary and to
   the AECMA Simplified English. This was to ensure that no obviously required words were omitted.
6. Used several standard and technical dictionaries to assign an appropriate definition for each word.
7. Looked for synonyms in a thesaurus. (Generally, when synonyms were found, the shorter word was
   retained.)
8. Checked the core vocabulary for antonyms. When the combination of not and another word would serve,
   the antonym was deleted. If a word could not be replaced or if the alternate construction was too awk-
   ward, the word was retained. (example: use “not complete” instead of “incomplete”)
9. Grouped the words by function. (The groupings he used were: Operations-Definite, Operations-Not Def-
   inite, Things-Definite, Things-Not Definite, Conditions-Definite, Conditions-Not Definite, Location,
   Function Words, Joining Words, Helping Words.)
10. Subdivided each groups into verbs, nouns, prepositions, etc. The words in each subdivision were then put
    in alphabetical order.
11. Used the words deleted from the original list to make a list of not-approved words. Example: “Conclu-
    sion: Use END”
To develop a technical word vocabulary Mr. Peterson did the following:
1. Prepared a complete parts list and a list of required tools and test equipment. Defined these part names
    and added them to the approved vocabulary.
2. Analyzed existing documents to identify the condition, process, and action words.
3. Made a list of words that described a technical process. Defined these words.
4. Made a list of words that described a condition affecting operation or maintenance. Defined these words.
5. Made a list of words that described an action required for operation or maintenance. Defined these
    words.
6. Reviewed the words and replaced them with words from the core vocabulary, where possible.
7. Added the words to the approved vocabulary.
