- main idea
- Related: topic sentence, supporting detail, summary
The central point a passage is built to communicate. It is broad enough to cover the whole text, not just one paragraph, and is usually stated in a single sentence.
- topic
- Related: main idea, thesis
The subject a passage is about, expressed as a word or short phrase. The topic answers what the text concerns, while the main idea states what the author claims about it.
- thesis
- Related: main idea, topic sentence
The controlling claim of a nonfiction piece, often placed near the beginning. Everything else in the text should support, explain, or qualify it.
- topic sentence
- Related: main idea, supporting detail
A sentence, usually first in a paragraph, that announces the paragraph's focus. It links the paragraph to the larger main idea and guides what details follow.
- supporting detail
- Related: main idea, evidence, illustration
A fact, example, statistic, or reason that explains or proves a broader claim. Details answer questions like who, what, when, and how much, rather than stating the point itself.
- summary
- Related: main idea, paraphrase
A brief restatement of a text's central points in your own words. A good summary keeps main ideas and drops minor examples, and it does not add personal opinion.
- paraphrase
- Related: summary, inference
Restating a short passage in different words while keeping the original meaning intact. It is narrower than a summary and preserves the source's level of detail.
- inference
- Related: implication, explicit detail, conclusion
A conclusion drawn from clues in the text plus ordinary reasoning, even though the text never states it outright. Valid inferences must be supported by the passage.
- implication
- Related: inference, tone, connotation
A meaning a writer suggests without stating directly, often through word choice or what is left unsaid. Readers detect implications by combining textual clues with background knowledge.
- explicit detail
- Related: inference, supporting detail
Information stated plainly in the text, requiring no guessing. Questions about explicit details are answered by locating the exact sentence that reports the fact.
- conclusion
- Related: inference, evidence
A judgment reached after weighing the passage's information. In reading questions, the best conclusion follows logically from the stated facts and does not overreach them.
- evidence
- Related: supporting detail, conclusion, claim
The specific material in a text that backs up a claim, such as data, quotations, examples, or expert statements. Strong evidence is relevant, specific, and sufficient.
- claim
- Related: evidence, argument
A statement the author asserts as true and expects readers to accept. Claims may be factual or arguable, and they require support to be persuasive.
- argument
- Related: claim, evidence, persuasion
A reasoned case in which a writer presents a claim and supports it with evidence and logical reasoning. An argument aims to persuade, not merely to describe.
- persuasion
- Related: argument, bias, rhetorical question
Writing intended to move readers toward a belief or action. It relies on appeals to logic, emotion, or the writer's credibility, and often addresses counterarguments.
- author's purpose
- Related: tone, audience, main idea
The reason a writer produced the text, commonly to inform, persuade, entertain, or instruct. Purpose shapes word choice, structure, and how much detail is included.
- tone
- Related: mood, connotation, author's purpose
The writer's attitude toward the subject, conveyed through word choice and sentence style. Tone might be critical, admiring, humorous, urgent, or neutral.
- mood

The feeling a passage creates in the reader, such as suspense, calm, or unease. Mood arises from setting, imagery, and rhythm rather than from the author's stated attitude.

- Related: author's purpose, tone
The intended readers of a text. Writers adjust vocabulary, formality, and assumed background knowledge depending on whether readers are experts, patients, students, or the general public.
- connotation

The emotional or cultural association a word carries beyond its literal meaning. For example, 'thrifty' sounds approving while 'stingy' sounds critical, though both concern spending.
- denotation
- Related: connotation
The literal, dictionary meaning of a word, separate from emotional associations. Reading questions sometimes ask you to distinguish denotation from connotation in a passage.
- bias
- Related: persuasion, fact versus opinion, objectivity
A slant or prejudice that favors one side, often shown through loaded words, omitted facts, or one-sided examples. Recognizing bias helps readers judge whether a source is balanced.
- objectivity
- Related: bias, fact versus opinion
A neutral stance in which a writer reports information without pushing a personal agenda. Objective writing favors verifiable facts and balanced coverage over emotional appeals.
- fact versus opinion
- Related: bias, evidence, claim
The distinction between statements that can be verified and statements that express beliefs, feelings, or judgments. Facts can be checked; opinions vary by person and need support.

The order in which events or steps occur. Signal words such as first, next, then, and finally help readers follow chronological or procedural order.

Determining what a word means as it is used in a specific sentence, since many words have several senses. The surrounding passage, not a memorized definition, decides the meaning.
- figurative language
- Related: metaphor, simile, imagery
Language that departs from literal meaning to create effect, including metaphor, simile, and personification. It shapes tone and requires interpretation rather than literal reading.
- metaphor

A direct comparison that states one thing is another without using like or as, such as calling memory a warehouse. Metaphors create meaning by transferring qualities across domains.

A comparison using like or as, such as 'the line moved like molasses.' Similes make descriptions vivid by linking an unfamiliar quality to something familiar.
