A word that expresses an action, occurrence, or state of being, such as run, become, or seem. Verbs change form to show tense and must agree with their subject.

Related: subject-verb agreement, tense, participle
adjective

A word that describes or limits a noun or pronoun, answering questions like what kind, which one, or how many. Examples include blue, careful, and several.

Related: adverb, modifier, comparative

pronoun

A word that stands in for a noun or noun phrase, such as he, they, it, or someone. Pronouns must refer clearly to a noun, called the antecedent, so readers know who or what is meant.

Related: antecedent, noun, case
antecedent

The noun or noun phrase that a pronoun refers back to. In the sentence 'Maya lost her keys,' Maya is the antecedent of her. An unclear antecedent makes a sentence confusing.

Related: pronoun, ambiguous reference

Related: predicate, verb, subject-verb agreement
predicate

The part of a sentence that says something about the subject, usually containing the verb and its objects or complements. In 'The dog barked loudly,' the predicate is 'barked loudly.'

Related: phrase, independent clause, subordinate clause
phrase

A group of related words that functions as a unit but lacks a subject and verb working together as a clause does. Examples include 'in the morning' and 'the tall building.'

Related: clause, modifier

Related: clause, subordinate clause, run-on sentence
subordinate clause

A clause that cannot stand alone because it begins with a subordinating word such as because, although, or when. It must be attached to an independent clause to form a complete sentence.

Related: clause, independent clause, fragment
