Language and Grammar
Clear, consistent language helps readers understand your meaning. This chapter covers spelling, terminology, sentence structure, and practical grammar choices.
4.1English in Different Places
English belongs to many places and communities. Choose the spelling and expressions that fit your voice and readers, then use them with care.
4.1.1Your English, Your Readers
There is no single variety of English everyone needs to use. American, Australian, British, Canadian, Indian, and other Englishes have their own histories and conventions. A difference is not automatically a mistake.
This site’s prose uses American spellings as part of the author’s voice. That is a choice for this site, not a rule for your writing. Use the variety that fits you and your readers.
American spelling: The color of the theater walls is gray.
British spelling: The colour of the theatre walls is grey.
When writing for people in several places, give context for local words and avoid ambiguous dates or measurements. See Writing Across Regions for comparisons.
4.1.2Choosing Spellings
Choose a regional spelling convention for a piece and use a matching dictionary. Keep a short note of recurring choices so you don’t have to settle them every time.
Names and quotations keep their original spelling. Dialogue may also reflect a speaker’s own way of using English.
4.1.3Finding a Useful Dictionary
Choose a dictionary that reflects the English you use. Merriam-Webster is useful for American English; Cambridge includes British and American usage; Macquarie focuses on Australian English. A regional dictionary can explain choices a spellchecker marks without context.
For a person’s name, follow their own spelling. For an unfamiliar subject, check a reliable reference and explain the term if your readers need it.
4.1.4Naming Apps and Browsers
Use a product’s recognizable name and match its capitalization. Add the maker’s name when it helps readers tell similar names apart.
Example: The page works in Chrome, Firefox, and Safari.
Describe actual compatibility rather than saying a page is “best viewed” in one browser.
4.2Third-Party and Specialized Terminology
4.2.1Third-Party Terms and Spelling
Follow the owner’s documentation for proprietary names and terms. Retain official spelling and capitalization, such as Microsoft Word, Google Workspace, iCloud, and Adobe InDesign. Provide context when readers may not recognize a name.
4.3Abbreviations, Acronyms, and Initialisms
An abbreviation is a shortened form. An acronym is read as a word; an initialism is read letter by letter. You don’t need to memorize the labels to make a useful choice: ask whether the short form will help your reader.
See also Abbreviations and Acronyms.
4.3.1Abbreviations
Spell out an unfamiliar term the first time it appears, followed by its abbreviation in parentheses when the abbreviation will be used again.
First occurrence: Bring your own bottle (BYOB) to the picnic.
Later: The invitation includes a BYOB reminder.
If the full phrase is short or appears only once, an abbreviation may not help. Consider your audience rather than defining every familiar short form automatically.
4.3.2Acronyms
An acronym uses letters from a phrase and is pronounced as a word. NASA is a familiar example. Use the established spelling: some acronyms, such as scuba, have become ordinary lowercase words.
Example: NASA shared new images of the Moon.
4.3.3Initialisms
An initialism is read letter by letter, such as DIY or RSVP. Use the established spelling and punctuation.
Correct: DIY
Avoid: D.I.Y.
Explain an initialism if your readers may not recognize it. Do not introduce several unfamiliar short forms in the same paragraph.
4.3.4Other Types of Abbreviations
Shortened words belong in everyday writing, too. Choose them when your readers will understand them and they fit your voice.
Contractions
Forms such as can’t and we’ll often make writing sound natural. Use the full form when you want emphasis or a more formal rhythm.
Blended words
A portmanteau joins parts of words, as in brunch. Explain an unfamiliar blend rather than expecting readers to guess.
Clipped forms
App, lab, and photo are familiar shortened words. A less familiar one may need context.
Symbols
A symbol such as % can save space. Use it consistently and explain it if its meaning may be unclear.
4.3.5Spelling Abbreviations and Acronyms
Spell out an unfamiliar term on first use if its short form will appear again. Use a familiar abbreviation without explanation when your audience will recognize it.
Example: a DIY project; an RSVP.
Choose a or an by pronunciation. Form ordinary abbreviation plurals without an apostrophe, and follow established capitalization rather than inventing a new form. In general prose, for example and that is may be clearer than unfamiliar Latin abbreviations.
4.4Verbs And Verb Forms
4.4.1Verbs
Choose a verb that tells the reader what happened. Active constructions often make a sentence more direct.
Active: Maya baked the bread.
Passive: The bread was baked by Maya.
Prefer a simple, precise verb when a longer phrase adds no meaning.
Avoid: We made a decision to leave.
Prefer: We decided to leave.
4.4.2Words Ending in -Ing
Words ending in -ing can describe an activity or an action in progress. Place them carefully so readers know who is doing what.
Ambiguous: Walking to the café, the rain soaked my coat.
Clearer: As I walked to the café, rain soaked my coat.
Do not remove every -ing form. Use the construction that makes the meaning clear.
4.4.3Contractions
Contractions often bring writing closer to speech. I’m, we’ll, and don’t can make a message feel more natural. The full form can slow the rhythm or add emphasis.
Conversational: I don’t think we’ll need a coat.
Emphatic: I do not want to miss this.
Choose the form that fits the moment. For writing with a prescribed format, check the conventions for that piece.
4.5Nouns and Pronouns
4.5.1Nouns
Use precise nouns when a vague word such as thing or stuff leaves readers guessing. The picnic basket tells readers more than the thing by the door.
4.5.2Pronouns
Make it clear who or what a pronoun refers to, especially when a sentence mentions more than one person.
Ambiguous: Alex called Jordan before they left.
Clearer: Before leaving, Alex called Jordan.
Use they for a person whose gender is unknown or irrelevant, and respect the pronouns a person uses.
4.5.3Possessives
Singular nouns
Add an apostrophe and s to form a singular possessive, including many names ending in s.
Example: the neighbor’s garden; James’s bicycle.
Plural nouns
For a plural ending in s, add the apostrophe after the s. For a plural that does not end in s, add an apostrophe and s.
Example: the neighbors’ gardens; the children’s books.
Names
Follow a consistent convention for names. Rephrase if a possessive form is awkward or unclear.
Example: James’s bicycle.
Example: the bicycle James rides.
Names of products and organizations
Check any relevant naming guidance. A phrase such as the settings in Photos may be clearer than an awkward possessive. Ordinary nouns do not need a special possessive rule simply because they once referred to a named feature.
See also Apostrophes.
4.5.4Plurals
Most nouns take -s or -es, but some change in other ways. A dictionary can help with unfamiliar plurals. Keep a term’s form consistent within your piece.
Regular: one fox, two foxes
Irregular: one child, two children
An apostrophe usually shows possession or a contraction, not an ordinary plural.
In many compound nouns, the main noun takes the plural ending. Check an unfamiliar form in a dictionary.
Compound plurals: mothers-in-law; runners-up
See Compounds and Prefixes for the different forms a compound can take.
4.6Sentence Structure
A sentence can hold one main clause or connect several ideas. A compound sentence joins two or more independent clauses, groups of words that could each stand as a complete sentence. This is a different use of compound from compound words and modifiers.
A compound sentence: The café was closed, so we made coffee at home.
A comma and a coordinating conjunction such as and, but, or so can join the clauses. A semicolon can connect closely related clauses without a conjunction. See Commas and Colons and Semicolons for examples.
4.6.1Misplaced Modifiers
Place a modifier near the word or phrase it describes. Changing its position can change the meaning.
Ambiguous: She only paints flowers on Sundays.
Clearer: She paints flowers only on Sundays.
Clearer: On Sundays, she paints only flowers.
The first revision limits the day. The second limits what she paints. Choose the wording that matches your meaning.
4.6.2Prepositions
A preposition can be the most natural way to end a sentence. Keep it when the sentence needs it; remove it when it only repeats a meaning.
Conversational: Who are you talking to?
More formal: To whom are you speaking?
Wordy: The basket is outside of the door.
Tighter: The basket is outside the door.
Both formal and conversational constructions can be clear. Choose for your voice rather than rearranging a sentence to satisfy a supposed ban.
4.7Articles
Choose a or an based on sound rather than spelling.
Example: a bicycle; a useful idea; an umbrella; an hour.
Use the for something specific or already identified.
Example: I borrowed a book. The book was about gardening.
Include articles where the sentence needs them, and leave them out of names that do not use them.
4.8Writing Clarity and Redundancy
4.8.1Avoid Redundancy
Remove words that repeat information without adding meaning.
Avoid: We will return back home after lunch.
Prefer: We will return home after lunch.
Avoid: The party is at 8 p.m. this evening.
Prefer: The party is at 8 this evening.
Repetition can be a deliberate choice for emphasis or rhythm. Keep it when it serves the writing.
4.8.2Parallelism in Writing
Use matching grammatical forms for items that play the same role in a sentence or list.
Correct: She enjoys reading, walking, and cooking.
Incorrect: She enjoys reading, walking, and to cook.
Keep wording and number formats consistent when you compare similar things.
Example: Bring 10 plates, 10 cups, and 6 napkins.
Use the same term for the same idea unless a change of wording improves the meaning or rhythm.
4.8.3Metalinguistic Awareness
When you discuss a word as a word, distinguish it from the rest of the sentence. Italics work well; quotation marks can help when italics aren’t available.
Example: The word style has several meanings.
Name a letter or punctuation mark when the character alone could be confusing.
Example: The letter A appears twice.
Example: Use an asterisk (*) to point to a note.
