main idea

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.

Related: topic sentence, supporting detail, summary
topic

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.

Related: main idea, thesis
thesis

The controlling claim of a nonfiction piece, often placed near the beginning. Everything else in the text should support, explain, or qualify it.

Related: main idea, topic sentence
topic sentence

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.

Related: main idea, supporting detail
supporting detail

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.

Related: main idea, evidence, illustration
summary

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.

Related: main idea, paraphrase
paraphrase

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.

Related: summary, inference
inference

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.

Related: implication, explicit detail, conclusion
implication

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.

Related: inference, tone, connotation
explicit 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.

Related: inference, supporting detail
conclusion

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.

Related: inference, evidence
evidence

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.

Related: supporting detail, conclusion, claim
claim

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.

Related: evidence, argument
argument

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.

Related: claim, evidence, persuasion
persuasion

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.

Related: argument, bias, rhetorical question
author's purpose

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.

Related: tone, audience, main idea
tone

The writer's attitude toward the subject, conveyed through word choice and sentence style. Tone might be critical, admiring, humorous, urgent, or neutral.

Related: mood, connotation, author's purpose
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: tone, imagery
audience

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.

Related: author's purpose, tone
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.

Related: denotation, tone, implication
denotation

The literal, dictionary meaning of a word, separate from emotional associations. Reading questions sometimes ask you to distinguish denotation from connotation in a passage.

Related: connotation
bias

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.

Related: persuasion, fact versus opinion, objectivity
objectivity

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.

Related: bias, fact versus opinion
fact versus opinion

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.

Related: bias, evidence, claim
sequence

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

Related: chronological order, transition, process
chronological order

Arrangement of information by time, from earliest to latest or the reverse. It is common in narratives, histories, and descriptions of procedures.

Related: sequence, transition
cause and effect

A text structure that explains why something happened and what resulted. Signal words include because, therefore, as a result, consequently, and leads to.

Related: sequence, compare and contrast, transition
compare and contrast

A structure that examines similarities and differences between two or more subjects. Signal words include similarly, likewise, unlike, whereas, and on the other hand.

Related: cause and effect, transition
transition

A word or phrase that connects ideas and signals how they relate, such as however, in addition, or for example. Transitions reveal the passage's logical organization.

Related: sequence, cause and effect, compare and contrast
reference

A pronoun or phrase that points back to an earlier noun, such as 'she' referring to a named patient. Tracking references prevents misreading who did what.

Related: context clue, sentence structure
context clue

Information surrounding an unfamiliar word that hints at its meaning, including definitions, examples, contrasts, or restatements nearby. Context clues let readers infer vocabulary without a dictionary.

Related: reference, inference
vocabulary in context

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.

Related: context clue, connotation
figurative language

Language that departs from literal meaning to create effect, including metaphor, simile, and personification. It shapes tone and requires interpretation rather than literal reading.

Related: metaphor, simile, imagery
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.

Related: simile, figurative language
simile

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.

Related: metaphor, figurative language
imagery

Descriptive language that appeals to the senses and creates a mental picture. Imagery often drives mood and can reveal a narrator's attitude toward a place or event.

Related: mood, figurative language
rhetorical question

A question posed for effect rather than to obtain an answer, used to emphasize a point or provoke thought. It often appears in persuasive writing.

Related: persuasion, argument
point of view

The perspective from which a text is told, such as first person, third-person limited, or third-person omniscient. Point of view controls what information the reader can access.

Related: author's purpose, tone
process

A text structure presenting steps in order to explain how something works or is done. Procedural passages often use imperative verbs and sequence signals.

Related: sequence, chronological order
illustration

An example or instance offered to clarify a general statement. Illustrations make abstract claims concrete and are a common form of supporting detail.
