Thesis statement

A single sentence, usually placed near the start of an essay, that states the central claim the writer will defend. It should be specific and arguable rather than a bare announcement of topic.

Related: Topic sentence, Argumentative essay, Controlling idea
Topic sentence

The sentence, often first in a paragraph, that names the paragraph's main point and ties it back to the essay's thesis. The remaining sentences supply evidence, explanation, or illustration for it.

Related: Thesis statement, Paragraph unity, Transition
Controlling idea

The central concept that governs an entire piece and limits what material belongs in it. Every paragraph should visibly support this idea, and anything off-topic is cut during revision.

Related: Thesis statement, Paragraph unity
Paragraph unity

The quality of a paragraph in which every sentence serves the stated main point. Sentences that drift to a new subject break unity and usually need to be moved or deleted.

Related: Topic sentence, Coherence, Controlling idea
Coherence

The quality that makes a piece read as a connected whole, achieved by logical order of ideas and by clear links between sentences and paragraphs. Readers should never have to guess how one point relates to the next.

Related: Transition, Paragraph unity, Cohesion
Cohesion

The surface-level linking of sentences through pronouns, repeated key words, and transitional phrases so that each sentence connects to the one before it. Cohesion works alongside coherence, which concerns overall logical flow.

Related: Coherence, Transition, Pronoun reference
Transition

A word, phrase, or sentence that signals the relationship between ideas, such as addition, contrast, cause, or sequence. Strong transitions clarify logic rather than merely decorate the prose.

Related: Coherence, Cohesion
Narrative writing

Prose that tells a story by presenting events, often in chronological order, with characters and a point of view. Effective narrative uses concrete detail and a clear sequence rather than summary alone.

Related: Chronological order, Point of view, Show, don't tell
Argumentative essay

An essay that takes a position on a debatable issue and supports it with reasons and evidence while acknowledging counterarguments. Its success depends on a clear claim, credible support, and logical organization.

Related: Thesis statement, Counterargument, Evidence
Counterargument

An opposing view that a writer raises and then answers in order to strengthen a position. Addressing it shows the writer has considered alternatives and makes the argument more credible.

Related: Argumentative essay, Rebuttal, Concession
Rebuttal

The response that refutes or weakens a counterargument after it has been presented. A rebuttal may show faulty reasoning, missing evidence, or a limited scope in the opposing claim.

Related: Counterargument, Concession, Logical fallacy
Concession

Admitting that part of an opposing view is valid before explaining why the writer's position still stands. A well-placed concession builds credibility, but overusing it can blur the essay's main claim.

Related: Counterargument, Rebuttal
Evidence

Facts, examples, statistics, expert testimony, or personal observations offered to support a claim. Evidence must be relevant, sufficient, and accurately reported to be persuasive.

Related: Argumentative essay, Citation, Anecdote
Anecdote

A brief story about a specific incident used to illustrate or support a point. Anecdotes can engage readers but are weak as sole evidence because one case does not prove a general claim.

Related: Evidence, Narrative writing
Chronological order

Organization that presents events in the order they occurred, from earliest to latest. It suits narratives, process descriptions, and historical accounts where sequence matters to understanding.

Related: Narrative writing, Transition
Order of importance

Organization that arranges points from least to most significant, or the reverse, so the strongest material lands where it has most impact. It is common in persuasive and explanatory writing.

Related: Thesis statement, Coherence
Point of view

The perspective from which a piece is told, such as first person, third-person limited, or third-person omniscient. Shifting perspective without reason confuses readers and weakens consistency.

Related: Narrative writing, Pronoun reference
Show, don't tell

A revision principle urging writers to render scenes through concrete sensory detail and action instead of summarizing emotions. It makes narrative and descriptive prose vivid and credible.

Related: Narrative writing, Word choice
Audience

The intended readers of a piece, whose knowledge, expectations, and attitudes shape tone, vocabulary, and how much background must be explained. Ignoring audience leads to prose that is too technical or too basic.

Related: Tone, Register, Purpose
Purpose

The writer's reason for composing a text, such as to inform, persuade, entertain, or explain a process. Purpose determines structure, evidence, and level of detail.

Related: Audience, Tone, Rhetorical mode
Tone

The attitude a writer conveys toward the subject and reader, for example formal, ironic, sympathetic, or urgent. Tone is created through word choice, sentence structure, and level of detail.

Related: Audience, Word choice, Register
Register

The level of formality in language, ranging from casual conversation to academic prose. Register should match the audience and occasion, and mixing levels unintentionally creates awkward inconsistency.

Related: Tone, Audience, Word choice
Word choice

The selection of words to convey precise meaning and appropriate connotation. Vague, inflated, or clichéd wording weakens writing, while exact verbs and nouns make prose clearer and more forceful.

Related: Connotation, Denotation, Tone
Connotation

The associations or emotional coloring a word carries beyond its literal meaning, such as the difference between thrifty and stingy. Writers choose among near-synonyms to control these associations.

Related: Denotation, Word choice
Denotation

The literal, dictionary meaning of a word, independent of the feelings it may evoke. Precision in denotation prevents ambiguity, while attention to connotation controls tone.

Related: Connotation, Word choice
Sentence variety

Mixing sentence lengths and structures, such as simple, compound, and complex forms, to keep prose readable and emphasize key ideas. Uniform short or long sentences quickly become monotonous.

Related: Sentence fragment, Comma splice, Parallelism
Parallelism

Presenting related ideas in matching grammatical form, as in a list of parallel verbs or phrases. Faulty parallelism forces readers to work out how items correspond and is a common revision target.

Related: Sentence variety, Modifier
Rhetorical mode

A pattern of development such as narration, description, comparison and contrast, cause and effect, definition, or persuasion. Modes can be combined, but each implies a characteristic organization.

Related: Purpose, Chronological order
Topic sentence placement

The position of a paragraph's main-idea sentence, which may open the paragraph, close it as a summary, or be implied. Placement is a stylistic choice, but clarity of the main point must never suffer.

Related: Topic sentence, Paragraph unity
Subject-verb agreement

The rule that a verb must match its subject in number and person, as in she writes versus they write. Errors typically arise with interrupting phrases, indefinite pronouns, and compound subjects.

Related: Pronoun-antecedent agreement, Collective noun
Pronoun-antecedent agreement

The requirement that a pronoun match its antecedent in number, gender, and person. Problems commonly occur with indefinite antecedents like everyone and with nouns joined by or and nor.

Related: Subject-verb agreement, Pronoun reference, Indefinite pronoun
Pronoun reference

The clarity with which a pronoun points back to a specific noun. Ambiguous, missing, or remote antecedents force readers to guess who or what is meant and should be revised.

Related: Pronoun-antecedent agreement, Modifier, Cohesion
Sentence fragment

A group of words punctuated as a sentence but lacking a subject, a complete verb, or an independent clause. Fragments can be repaired by attaching them to a nearby sentence or supplying the missing part.

Related: Run-on sentence, Comma splice, Independent clause
Run-on sentence

Two or more independent clauses joined without adequate punctuation or a conjunction. It can be fixed with a period, a semicolon, or a coordinating conjunction plus comma.

Related: Comma splice, Sentence fragment, Independent clause
Comma splice

Joining two independent clauses with only a comma, which is too weak to separate them. Repair options include a period, a semicolon, or a comma plus coordinating conjunction.

Related: Run-on sentence, Independent clause, Semicolon
Independent clause

A group of words containing a subject and a complete verb that can stand alone as a sentence. Recognizing it is essential for punctuating compound and complex sentences correctly.

Related: Dependent clause, Run-on sentence, Semicolon
Dependent clause

A clause with a subject and verb that cannot stand alone because it begins with a subordinating word or relative pronoun. It must be attached to an independent clause to form a complete sentence.

Related: Independent clause, Sentence fragment, Subordination
Modifier

A word, phrase, or clause that describes another element in the sentence. A misplaced or dangling modifier attaches to the wrong word or to nothing, producing confusing or unintentionally comic meaning.

Related: Pronoun reference, Parallelism
Semicolon

A punctuation mark used mainly to separate two closely related independent clauses or to divide items in a complex list. It signals a tighter connection than a period but a stronger break than a comma.

Related: Comma splice, Independent clause, Colon
Colon

A punctuation mark that introduces an explanation, list, or quotation after a complete clause. It should not separate a verb from its object or a preposition from its object.

Related: Semicolon, Independent clause
Apostrophe use

The conventions for forming possessives and contractions with an apostrophe, such as the dog's bowl or it's raining. Confusing possessive its with contraction it's is a frequent error.

Related: Subject-verb agreement, Word choice
Capitalization

The conventions governing uppercase letters, including proper nouns, sentence beginnings, and titles. Overcapitalizing common nouns or failing to capitalize proper nouns are common mechanical errors.

Related: Punctuation, Word choice
Punctuation

The system of marks that clarifies sentence structure, pace, and meaning. Correct use of commas, semicolons, colons, and dashes prevents misreading and demonstrates control of written English.

Related: Semicolon, Colon, Comma splice
Citation

A reference identifying the source of a quotation, statistic, or idea, usually including author, title, and publication details. Citations let readers verify claims and avoid plagiarism.

Related: Plagiarism, Paraphrase, Source evaluation
Plagiarism

Presenting someone else's words or ideas as one's own, whether by copying, paraphrasing too closely, or omitting attribution. Even unintentional failure to cite a source counts as plagiarism.

Related: Citation, Paraphrase, Direct quotation
Paraphrase

Restating a source's idea in one's own words and sentence structure while preserving the meaning. A legitimate paraphrase still requires a citation because the idea belongs to the original author.

Related: Citation, Direct quotation, Plagiarism
Direct quotation

Reproducing a source's exact words inside quotation marks, with an accompanying citation. Quotations should be used selectively for distinctive phrasing or authority, not to replace the writer's own explanation.

Related: Paraphrase, Citation, Plagiarism
Source evaluation

Judging whether information is credible, current, relevant, and authoritative before relying on it. Criteria include the author's expertise, the publisher, the date, and the evidence behind the claims.

Related: Citation, Evidence
Logical fallacy

A flaw in reasoning that makes an argument unreliable, such as attacking a person instead of a claim or assuming a cause from sequence. Recognizing fallacies helps candidates spot weak reasoning in passages.

Related: Rebuttal, Argumentative essay
Indefinite pronoun

A pronoun such as everyone, each, few, or none that refers to an unspecified person or thing. Many are singular and take singular verbs, which often creates agreement errors.

Related: Pronoun-antecedent agreement, Subject-verb agreement
Collective noun

A singular noun naming a group, such as team, committee, or family. In American English it normally takes a singular verb when the group acts as one unit.

Related: Subject-verb agreement
Subordination

Expressing the relative importance of ideas by placing less important ones in dependent clauses and main ones in independent clauses. It prevents choppy prose and clarifies emphasis.

Related: Dependent clause, Sentence variety
