4.1 Subject-Verb Agreement, Compound Subjects & Consistent Tenses

4.1 Subject-Verb Agreement, Compound Subjects & Consistent Tenses

In official police documentation—such as incident logs, witness statements, search warrant applications, and court affidavits—grammatical precision is directly linked to legal clarity. A subject-verb disagreement or an erratic shift in verb tense can introduce ambiguity into official testimony, allowing defence attorneys to challenge the credibility of a report. For candidates preparing for the Jamaica Constabulary Force (JCF) Entrance Examination, mastering subject-verb agreement and tense consistency is essential for scoring high on the English Language and Communication section.

Core Principles of Subject-Verb Agreement

The fundamental rule of subject-verb agreement states that a verb must agree in number (singular or plural) with its grammatical subject. A singular subject takes a singular verb, while a plural subject takes a plural verb.

• Singular Subject + Singular Verb: The Constable patrols the sector daily.
• Plural Subject + Plural Verb: The Constables patrol the sector daily.

Navigating Intervening Words and Phrases

Errors frequently occur when words or phrases separate the subject from the verb. Prepositional phrases or qualifying expressions—such as along with, as well as, together with, in addition to, including, or accompanied by—do not change the number of the main subject. You must ignore these intervening phrases when determining whether to use a singular or plural verb.

Consider the following example:

Incorrect: The Sergeant, along with three district constables, were dispatched to the scene. Correct: The Sergeant, along with three district constables, was dispatched to the scene.

In this sentence, the true subject is the singular noun Sergeant. The prepositional phrase along with three district constables is parenthetical and does not make the subject plural.

Compound Subjects: 'And', 'Or', and 'Neither/Nor'

Compound subjects consist of two or more nouns or pronouns joined by a conjunction. The choice of verb depends entirely on the specific conjunction used.

Subjects Joined by 'And'

When two or more singular subjects are joined by and, they form a plural compound subject and require a plural verb:

• Constable Brown and Corporal Grant were assigned to the mobile unit.
• The driver and the front-passenger were detained for questioning.

Exception: When two singular nouns joined by and refer to the same person or form a single unified concept, use a singular verb:

• The station commander and investigating officer was present. (If both titles refer to one individual).
• Breach and entry was executed according to standard operating procedure.

Subjects Joined by 'Or', 'Nor', 'Either...Or', or 'Neither...Nor'

When subjects are joined by or, nor, either...or, or neither...nor, the verb must agree with the subject closest to the verb (the rule of proximity).

1. Singular + Singular: Neither the suspect nor his accomplice was willing to cooperate.
2. Plural + Plural: Neither the suspects nor their accomplices were willing to cooperate.
3. Mixed Subjects (Plural closest to verb): Neither the Sergeant nor the constables were informed of the schedule change.
4. Mixed Subjects (Singular closest to verb): Neither the constables nor the Sergeant was informed of the schedule change.

Collective Nouns in Law Enforcement Contexts

Collective nouns name a group of individuals or items acting as a single unit. Common collective nouns in law enforcement include force, squad, unit, team, jury, division, committee, and crew.

The Rule of Unit vs. Individuals

• Unified Action (Singular Verb): When the group acts as a single, cohesive entity performing one action, use a singular verb.
  • The Jamaica Constabulary Force maintains high standards of integrity.
  • The Quick Response Team has cleared the intersection.
• Individual Actions (Plural Verb): When the members of the group act as separate individuals performing separate tasks, use a plural verb.
  • The forensic team were putting on their protective suits. (Focuses on individual members putting on separate garments).
  • The jury were divided in their opinions. (Focuses on differing individual viewpoints).

In standard police report writing, collective entities usually act as single units; however, candidates must recognize when context shifts focus to individual members.

Verb Tense Consistency in Incident Logs and Official Reports

Police reports must maintain logical, consistent verb tenses. Because an incident log records events that occurred in the past, the baseline narrative tense must remain in the past tense.

Avoiding Arbitrary Tense Shifts

Unintended switching between present tense and past tense within the same narrative creates confusion regarding the sequence of events.

Unacceptable Shift: Constable Reid approached the vehicle at 14:00 hours. He asks the driver for his license, but the driver refused to comply and drives away quickly. Corrected Log Entry: Constable Reid approached the vehicle at 14:00 hours. He asked the driver for his license, but the driver refused to comply and drove away quickly.

Expressing Prior Events: The Past Perfect Tense

When describing an action that was completed before another past action occurred, use the past perfect tense (had + past participle).

• Correct Sequence: Before Constable Reid arrived at the premises, the suspect had concealed the weapon in the shrubbery.
  • First Event (Past Perfect): Suspect had concealed the weapon.
  • Second Event (Simple Past): Constable Reid arrived.

Police Report Writing Best Practices Checklist

1. Identify the True Subject: Strip away prepositional phrases (of the suspects, in the vehicles) to locate the actual noun governing the verb.
2. Check Conjunctions: Verify whether subjects are connected by and (plural) or either/or (agree with the closest subject).
3. Anchor the Narrative Tense: Maintain simple past tense for the main narrative sequence; use past perfect only to establish prior background actions.
4. Verify Collective Nouns: Ensure collective terms like the division or the squad take singular verbs when acting as single organizational bodies.
