- Classic Learning Test (CLT)
- An online college-admissions exam from Classic Learning Initiatives — an alternative to the SAT and ACT, scored on a 0–120 composite.
- Composite score
- The CLT's overall score on a 0–120 scale, formed by adding the three section subscores (each 1–40); the score colleges receive.
- Percentile
- A ranking showing the percentage of test-takers a score equals or exceeds; reported with the CLT composite.
- Main idea
- The central point a passage is built to make — broad enough to cover the whole text but specific enough to exclude details.
- Topic
- What a passage is about, as distinct from the main idea, which is what the passage says about that topic.
- Inference
- A conclusion a passage strongly implies but does not state outright; it must be supported by evidence in the text.
- Vocabulary in context
- A word's meaning as used in the passage, which can differ from its most common dictionary definition.
- Tone
- The author's attitude toward the subject, conveyed through word choice, detail, and style (e.g., reverent, critical, ironic).
- Mood
- The feeling or atmosphere a passage creates in the reader, as distinct from the author's tone.
- Connotation
- The emotional or implied meaning a word carries beyond its literal definition (denotation).
- Denotation
- The literal, dictionary meaning of a word, apart from any emotional associations.

- The CLT's second section — 40 questions in about 35 minutes, editing passages for conventions and rhetoric.
- Standard English conventions
- The rules of grammar, usage, and mechanics the Grammar/Writing section tests.
- Subject-verb agreement
- A verb must match its subject in number — singular subject, singular verb; plural subject, plural verb.
- Pronoun-antecedent agreement
- A pronoun must match the noun it refers to in number and gender.
- Pronoun case
- Using the correct form of a pronoun — subjective (I, who), objective (me, whom), or possessive (my, whose).
- Modifier
- A word or phrase that describes another part of a sentence.
- Misplaced modifier
- A modifier positioned next to the wrong word, so it appears to describe the wrong thing.
- Dangling modifier
- A modifier whose intended subject is missing from the sentence, so it has nothing logical to describe.
- Dangling participle
- A participial phrase that doesn't logically attach to the subject — 'Running to catch the bus, her shoe fell off.'
- Parallel structure
- Using the same grammatical form for items in a series or comparison — 'reading, writing, and hiking.'
- Independent clause
- A group of words with a subject and verb that can stand alone as a complete sentence.
- Dependent (subordinate) clause
- A clause with a subject and verb that cannot stand alone — it begins with a subordinating word like 'because' or 'when.'
- Sentence fragment
- A group of words punctuated as a sentence but missing a subject, verb, or complete thought.
- Run-on sentence
- Two independent clauses joined with no punctuation or conjunction between them.
- Comma splice
- Joining two independent clauses with only a comma; fix it with a period, semicolon, conjunction, or subordination.
- Coordinating conjunction
- A word joining equal grammatical elements — for, and, nor, but, or, yet, so (FANBOYS).
- Subordinating conjunction
- A word that begins a dependent clause and links it to a main clause — because, although, when, if.
- Correlative conjunction
- A pair of words that work together — not only ... but also, either ... or, neither ... nor; the parts must be parallel.
- Semicolon
- Joins two closely related independent clauses, or separates list items that already contain commas.
- Colon
- Introduces a list, explanation, or example after a complete independent clause.
- Apostrophe
- Marks possession (the dog's bone) or a contraction (it's = it is); not used for simple plurals.
- Oxford (serial) comma
- The comma before the final 'and' in a list — 'apples, oranges, and bananas.'
- Em dash
- A punctuation mark that sets off an abrupt break or parenthetical element with emphasis.
- Verb tense consistency
- Keeping verb tenses consistent within a sentence or passage unless a shift in time requires a change.
- Past perfect tense
- Shows that one past action was completed before another past action — 'he had finished before she arrived.'
- Active voice
- The subject performs the action — 'the committee made the decision'; usually clearer and more concise.
- Passive voice
- The subject receives the action — 'the decision was made by the committee'; uses 'to be' plus a past participle.
- Conciseness
- Expressing an idea in as few words as needed; wordiness and redundancy are errors even when grammatical.
- Redundancy
- Needlessly repeating an idea — 'past history,' 'free gift'; the CLT rewards cutting it.
- Transition word
- A word or phrase that signals the logical relationship between ideas — however, therefore, moreover.
- Its vs. it's
- 'Its' is possessive (the cat licked its paw); 'it's' is the contraction of 'it is.'
- Affect vs. effect
- 'Affect' is usually a verb (to influence); 'effect' is usually a noun (a result).
- Who vs. whom
- 'Who' is a subject (who called?); 'whom' is an object (to whom did you speak?).
- Antecedent
- The noun a pronoun refers back to; pronoun and antecedent must agree.
