Subject-verb agreement can be tricky with certain subject types. Basic rules are that singular subjects take singular verbs ending in "s" while plural subjects take plural verbs without "s." However, collective nouns like "army" or "equipment" are singular even if plural. Pronouns like "you" and measurements like "minutes" are also singular. Verbs agreeing with the true subject can be missed if another noun is introduced by "of." Nouns ending in "s" like "physics" are also singular. Understanding these exceptions is important for proper subject-verb agreement.
