Subject-Verb Agreement
The verb must agree with its subject in number (singular or plural). The key rule: find the true grammatical subject — ignore all intervening prepositional phrases, relative clauses, or parenthetical expressions between the subject and the verb.
Singular → singular verb
The manager is in a meeting.
Plural → plural verb
The managers are in a meeting.
Intervening phrases
Subject + (with / along with / as well as / in addition to / together with) + noun — verb agrees with SUBJECT, not the added noun
Inverted sentences
There is / are ... — verb agrees with the noun that follows (There are three issues.)
The results of the audit was released.
The results ... were released.
A number of employees is absent.
A number of employees are absent.
