Verb Voice and Mood Review

By this stage, you already recognize active and passive voice and the three verb moods, indicative, imperative, and subjunctive. This review shifts the focus from identifying these forms in isolation to diagnosing and correcting errors as they appear on exams: mismatched conditional verbs, unjustified passive constructions, and mood shifts that undermine the logic of a sentence or paragraph.

Standardized assessments and timed essays reward the ability to catch these errors quickly and revise them without altering the intended meaning. The strategies below treat voice and mood as an integrated editing skill rather than two separate grammar topics.

A sentence is not incorrect simply because it is passive; passive voice is a legitimate stylistic choice when the performer of the action is unknown, irrelevant, or deliberately de-emphasized, as in "The bridge was completed in 1932." An error occurs when passive voice obscures a performer that the sentence actually needs, creates an ambiguous or dangling agent, or produces the kind of wordiness that exam graders penalize.

Consider the flawed sentence: "Mistakes were made during the negotiation process." On an exam, this construction is often flagged because it hides responsibility that the surrounding context requires. The correction demands identifying the missing subject and restoring it: "The negotiators made several mistakes during the process." Practice this diagnosis by asking two questions of any passive sentence: who or what is actually performing the action, and does the passage lose necessary information by omitting that performer.

Indicative mood states facts and asks questions, imperative mood issues commands, and subjunctive mood expresses conditions contrary to fact, wishes, or recommendations. Exam items most often test subjunctive mood, because its verb forms deviate from ordinary agreement rules and are therefore easy to get wrong under time pressure.

The most frequent subjunctive error involves the verb "to be" in hypothetical conditions. The incorrect form "If I was taller, I would have made the team" should read "If I were taller, I would have made the team," since the clause describes a condition that is not actually true. A second common error appears after verbs of demand, recommendation, or necessity, such as "insist," "require," or "suggest": "The committee insisted that the report was revised" should be corrected to "The committee insisted that the report be revised," because the subjunctive form after "insisted that" drops the usual "-s" or "was" agreement entirely.

A subtler category of error occurs when a sentence or passage begins in one mood and shifts into another without justification, breaking the logical thread for the reader. Consider: "Close the laboratory door, and you should record the temperature every hour." The sentence opens in imperative mood ("Close the door") but shifts into indicative mood ("you should record"), producing an inconsistency that many grammar sections are designed to test. A consistent revision keeps both instructions imperative: "Close the laboratory door, and record the temperature every hour."

The figure below summarizes how to isolate this kind of error: locate the mood established at the start of the sentence, identify where the verb form changes, and revise the second verb to match the first.

Exam passages frequently combine several errors in a short span, requiring you to work through voice and mood systematically. Consider this uncorrected excerpt: "The lab results were reviewed by the technician yesterday. If the sample was contaminated, the entire batch will be discarded, and discard the equipment logs too."

Three separate issues appear here. First, the opening sentence is passive without justification, since the technician is a known, relevant performer; it should read "The technician reviewed the lab results yesterday." Second, the conditional clause needs subjunctive mood because it describes a hypothetical, not a confirmed, contamination: "if the sample was contaminated" should become "if the sample were contaminated." Third, the final clause shifts abruptly into imperative mood ("discard the equipment logs") after two indicative statements; consistency requires "the equipment logs will be discarded too."

Working through each clause separately, rather than revising the whole passage at once, keeps the correction process manageable under exam conditions. For further practice refining these choices in your own writing rather than only on test items, see Mastering Voice and Mood in Writing.

Active Voice: A construction in which the subject performs the action of the verb.

Passive Voice: A construction in which the subject receives the action, often paired with a "by" phrase or an omitted performer.

Unjustified Passive: A passive construction that hides a performer the sentence actually needs, treated as an error on most exams.

Indicative Mood: The mood used to state facts, opinions, or questions.

Imperative Mood: The mood used to issue commands, requests, or instructions.

Subjunctive Mood: The mood used for hypothetical conditions, wishes, and clauses following verbs of demand or recommendation.

Mood Shift: An unjustified change from one verb mood to another within a sentence or passage.

Effective review sessions combine identification with revision: locate the error, name whether it is a voice problem or a mood problem, and rewrite the sentence so the correction reads naturally rather than awkwardly. Timed practice with short passages, rather than isolated sentences, mirrors how these errors actually appear on assessments, since a single flawed clause can affect the logic of everything around it.
