- main idea
- Related: topic sentence, supporting detail, summary
The central point a passage conveys about its topic, supported by most of its details. Readers identify it by asking what the whole text, not just one paragraph, is saying.
- supporting detail
- Related: main idea, inference
A specific fact, example, statistic, or reason that explains, illustrates, or proves a passage's main idea. Details answer who, what, when, where, why, or how questions about the central claim.
- inference
- Related: main idea, explicit statement
A conclusion drawn from evidence in the text plus the reader's background knowledge, rather than from a statement made outright. Valid inferences stay within what the text logically supports.
- explicit statement
- Related: inference, textual evidence
Information stated directly in a text, leaving no gap for the reader to fill. Distinguishing it from implied meaning helps candidates answer detail questions accurately without overreaching.
- textual evidence
- Related: inference, paraphrase
Quotations, paraphrases, or specific references from a passage used to justify an answer or claim. Strong evidence is precise, relevant to the question, and cited accurately without distortion.
- author's purpose
- Related: tone, rhetorical mode
The reason a writer produces a text, such as to inform, persuade, entertain, or explain. Purpose shapes word choice, structure, and which details the writer includes or omits.
- tone
- Related: mood, diction, author's purpose
The writer's attitude toward the subject, revealed through diction, syntax, and imagery. Tone differs from mood, which describes the feeling a reader experiences while reading.
- mood
- Related: tone, imagery
The emotional atmosphere a text creates for its reader, built through setting, imagery, and word choice. Mood is the reader's felt response, while tone is the writer's expressed attitude.

A recognizable pattern of organization such as narration, description, exposition, or argument. Recognizing the mode helps readers predict how ideas will be arranged and what evidence to expect.
- compare and contrast
- Related: rhetorical mode, transition
An organizational pattern that examines similarities and differences between two or more subjects. Signal words such as similarly, whereas, and in contrast reveal the structure to careful readers.
- summary

A brief restatement of a text's main points in the reader's own words, omitting minor details and personal opinion. A good summary preserves proportion, giving more space to central ideas than to trivia.
- paraphrase
- Related: summary, textual evidence
A restatement of a specific passage's meaning in different words while retaining its full sense and level of detail. Unlike summary, paraphrase does not condense the original.
- bias
- Related: connotation, author's purpose
A slant or partiality in a text that favors one side, often through loaded language, selective evidence, or omitted viewpoints. Detecting bias requires noticing what the writer leaves out as well as what is included.
- thesis
- Related: topic sentence, argument
The controlling claim of an essay, usually stated in one or two sentences near the beginning. A strong thesis is specific, arguable, and previews the line of reasoning that follows.

- Related: thesis, main idea
A sentence, usually first in a paragraph, announcing the paragraph's central point and linking it to the larger thesis. It governs the relevance of every detail in that paragraph.
- transition

A word, phrase, or sentence that connects ideas and signals relationships such as cause, contrast, or sequence. Effective transitions guide readers smoothly from one point to the next.

A reasoned case that supports a claim with evidence and addresses opposing views. A sound argument states its position clearly, provides relevant support, and acknowledges counterarguments.
- claim
- Related: argument, evidence
A statement the writer asserts as true and must defend with evidence. Claims differ from facts in that they are debatable and require support to be persuasive.

An opposing view that a writer acknowledges and then answers. Including a counterargument strengthens credibility by showing the writer has considered alternative positions fairly.
- refutation
- Related: counterargument, argument
The portion of an argument that demonstrates why an opposing view is weak or mistaken. It typically follows the concession of a counterargument and restates the writer's position.

The emotional or cultural associations a word carries beyond its literal meaning. Writers exploit connotation to create tone and persuade, so readers must notice the flavor words add.
