main idea

The most important point a text makes about its topic. It is what the author most wants readers to understand after finishing the passage, and it is usually stated or strongly suggested in the opening or closing sentences.

Related: topic, supporting detail, summary
topic

The subject a text is about, expressible in a word or short phrase. Topic differs from main idea because it names what is discussed, while the main idea states what the author claims about it.

Related: main idea, supporting detail
supporting detail

A fact, example, reason, or description that helps prove or explain the main idea. Good readers check whether each detail actually connects to the point the author is making about the topic.

Related: main idea, evidence, summary
summary

A brief retelling of a text that includes only the most important ideas and events, in the reader's own words. A summary leaves out minor details and keeps the original order of events clear.

Related: main idea, supporting detail, paraphrase
theme

A message or lesson about life that a story conveys, such as the value of honesty or the importance of perseverance. Themes are rarely stated outright; readers infer them from what characters do and learn.

Related: lesson, character trait, inference
lesson

The specific piece of advice or understanding a character, and often the reader, gains by the end of a story. A lesson is stated more directly than a theme and often follows a character's mistake.

Related: theme, character trait
character trait

A word describing a character's lasting personality, such as brave, selfish, or curious. Readers identify traits by noticing what a character says, does, and thinks across the whole story, not just once.

Related: character motivation, theme, dialogue
character motivation

The reason a character acts or feels a certain way, such as fear of failing or a wish to help a friend. Motivations are usually implied and must be inferred from dialogue, actions, and events.

Related: character trait, inference, plot
plot

The sequence of events in a story, usually built from a problem, rising action, a turning point, and a resolution. Understanding plot order helps readers explain why later events happen.

Related: problem and solution, resolution, sequence
problem and solution

A text structure in which an author presents a difficulty and then explains how it is or could be fixed. Recognizing this pattern helps readers track why events occur and how the text is organized.

Related: plot, resolution, text structure
resolution

The part of a story where the central problem is settled and the action comes to a close. The resolution often reveals what a character learned or how relationships changed.

Related: plot, problem and solution, lesson
sequence

The order in which events or steps happen in a text. Signal words such as first, next, then, and finally help readers follow chronological order in stories and informational passages.

Related: plot, text structure, cause and effect
cause and effect

A text structure that explains why something happened and what resulted. Words such as because, so, since, and as a result signal these links, which readers use to connect events logically.

Related: sequence, text structure, inference
compare and contrast

A text structure that shows how two or more things are alike and different. Signal words include both, also, unlike, and however, and organizers like Venn diagrams help readers sort these similarities and differences.

Related: text structure, text features
text structure

The way an author organizes information in a passage, such as sequence, cause and effect, compare and contrast, or problem and solution. Noticing structure helps readers predict what comes next and locate key information.

Related: compare and contrast, cause and effect, text features
text features

Parts of a passage beyond the main sentences that help readers find and use information, including headings, captions, bold words, diagrams, and a glossary. Readers should scan these before and during reading.

Related: text structure, caption, glossary
caption

A short line of text placed under or beside a picture or diagram that explains what it shows. Captions often supply details the main passage does not state, so they deserve careful reading.

Related: text features, diagram
diagram

A labeled drawing that shows the parts of something or how a process works. Readers use labels and arrows in a diagram to understand information that words alone might make confusing.

Related: caption, text features
glossary

A list, usually at the back of a book, that gives the meanings of important or difficult words from the text. A glossary is a text feature that supports vocabulary and comprehension while reading.

Related: text features, context clues
context clues

Hints in the words and sentences around an unfamiliar word that help a reader figure out its meaning. Clues may be definitions, examples, synonyms, antonyms, or the overall sense of the sentence.

Related: glossary, prefix, suffix
prefix

A word part added to the beginning of a base word that changes its meaning, such as un- in unhappy or re- in rewrite. Knowing common prefixes helps readers decode unfamiliar words.

Related: suffix, root word, context clues
suffix

A word part added to the end of a base word that changes its meaning or its part of speech, such as -less in fearless or -ful in hopeful. Recognizing suffixes supports word solving and spelling.

Related: prefix, root word
root word

The basic word that remains after prefixes and suffixes are removed, such as help in unhelpful. Identifying the root helps readers connect related words and guess meanings of longer ones.

Related: prefix, suffix
synonym

A word that means nearly the same as another word, such as happy and glad. Recognizing synonyms helps readers understand comparisons and avoid repeating the same word in writing.

Related: antonym, context clues
antonym

A word that means the opposite of another word, such as early and late. Antonyms often appear as contrast clues in a sentence, helping readers work out an unfamiliar word's meaning.

Related: synonym, context clues
inference

A conclusion a reader draws by combining clues in the text with what the reader already knows. An inference is not stated directly, so it must be supported by evidence from the passage.

Related: evidence, character motivation, prediction
evidence

Specific words, sentences, or details from a passage that support an answer or claim. Strong answers point to evidence rather than relying on personal opinion or general knowledge alone.

Related: inference, supporting detail
prediction

A thoughtful guess about what will happen next, based on clues in the text and the reader's prior knowledge. Predictions should be revised as new information appears in the passage.

Related: inference, evidence

Related: point of view, dialogue
