4.1 Parts of Speech, Grammar & Usage

Parts of Speech, Grammar, and Usage

The Language Use and Vocabulary category is 25% of Praxis English Language Arts: Content Knowledge (5038) — roughly 32 to 33 of the 130 selected-response items. Grammar and usage questions ask you to identify an error, choose the correct form, or classify how a word functions. Because 5038 has no essay (that is the 5039 exam), every grammar point is tested through recognition, so you must be able to spot the rule at a glance rather than merely write correctly.

The Eight Parts of Speech

Every English word plays one of eight roles, and the same word can shift roles depending on its position in the sentence.

Test writers love function over form: the word 'running' is a verb in 'she is running', a noun (gerund) in 'running is healthy', and an adjective (participle) in 'running water'. Decide the part of speech by the slot the word fills, not by its ending.

Subject-Verb Agreement

A verb must agree with its subject in number. The classic traps are:

• Intervening phrases: ignore words between the subject and verb. 'The box of chocolates is on the table' — the subject is 'box' (singular), not 'chocolates'.
• Indefinite pronouns: each, either, neither, everyone, anybody, one, and no one are singular ('Each of the students is ready'). Both, few, many, and several are plural. Some, all, none, and most take their number from the object of the phrase ('Some of the pie is gone' versus 'Some of the cookies are gone').
• Compound subjects joined by and are plural; joined by or/nor, the verb agrees with the nearer subject ('Neither the coach nor the players were late').
• Collective nouns (team, jury, class) are singular when acting as one unit ('The jury has reached a verdict').

Pronoun-Antecedent Agreement and Case

A pronoun must match its antecedent in number, gender, and person. 'Each of the writers submitted his or her draft' — 'each' is singular, so a singular pronoun follows, although many 2026 style guides now also accept singular they.

Pronoun case depends on the pronoun's job:

Isolate the tricky pronoun to test it: 'between you and (I/me)' is the object of a preposition, so use me. For who versus whom, substitute he/him: if 'he' fits, use who; if 'him' fits, use whom ('Whom did you call?' becomes 'you called him').

Verb Tense, Mood, and Voice

• Tense must stay consistent unless the time frame genuinely shifts. The perfect tenses mark action completed relative to another time ('She had left before we arrived').
• Mood: the indicative states facts, the imperative gives commands, and the subjunctive expresses wishes, hypotheticals, or demands. After verbs like recommend, suggest, insist, and ask, use the base verb: 'The board recommended that he be promoted'. For contrary-to-fact wishes, use were: 'If I were you...'.
• Voice: the active voice (subject acts) is usually preferred; the passive voice (subject is acted upon) hides or de-emphasizes the actor. 'The boy read the book' (active) versus 'The book was read by the boy' (passive).

Modifiers and Common Usage Errors

Use adjectives to modify nouns and adverbs to modify verbs, adjectives, and adverbs: 'She sang well' (adverb), not 'She sang good'. Good is an adjective; well is the adverb (except when 'well' means healthy). Use the comparative (-er/more) for two items and the superlative (-est/most) for three or more.

High-frequency usage confusions the exam recycles:

• its (possessive) versus it's (it is)
• affect (verb, to influence) versus effect (noun, a result)
• fewer (count nouns) versus less (mass nouns) — 'fewer errors, less confusion'
• lay (needs a direct object) versus lie (takes no object)
• who for people versus that/which for things

Worked Error-Identification Item

Consider: 'Neither the manager nor the employees was aware of the change.' The compound subject uses nor, so the verb agrees with the nearer subject, 'employees' (plural), which requires were. On test day, scan first for the real subject, then apply the single agreement rule that governs it — the intervening noun is almost always a distractor.

More Usage Traps to Memorize

Beyond agreement, 5038 recycles a short list of usage errors worth memorizing cold. Double negatives are nonstandard: 'She did not do nothing' should be 'She did not do anything'. Double comparatives are wrong too: use 'more careful' or 'carefuller' is incorrect — say 'more careful', never 'more carefuller'. Confusing adjective and adverb forms after linking versus action verbs is common: after a linking verb use an adjective ('The soup tastes good'), but after an action verb use an adverb ('She writes well'). Comparative forms also demand logical completeness: 'This novel is longer than any in the series' wrongly compares the novel to itself; write 'longer than any other in the series'.

Second Worked Usage Item

Consider: 'The effect of the new rules were felt immediately.' The subject is 'effect' (singular); 'of the new rules' is a prepositional phrase that cannot supply the subject, so the verb must be was, not 'were'. Note also the meaning trap: effect here is the correct noun (a result), whereas affect would be the verb form. Reading each item twice — once for the true subject and once for the intended word choice — catches both the agreement error and the homophone confusion that distractors exploit.
