Compound subjects have at least two parts joined by or . . . nor, not only . . . but also, or and, as in snacks and fruit juice, and each part may be singular or plural. A plural subject has just one word as the simple subject, but that word is plural (like plates). Finally, a collective subject contains a simple subject representing a group (such as jury, which describes a group of twelve); the collective subject may be singular (jury) or plural (juries).
Compound subjects refer to multiple subjects that are joined by coordinating conjunctions such as "and" or "or," while plural subjects refer to subjects that are inherently plural and do not require conjunctions. Collective subjects refer to a single entity that is made up of multiple individuals or parts.
"Do" is used with plural subjects and "does" is used with singular subjects in present simple tense. For example, "I do" and "He does."
"Belong" is used with plural subjects (e.g. "They belong to the team"), while "belongs" is used with singular subjects (e.g. "She belongs in the group").
A plural noun represents more than one of something. For example, 'flowers' is plural for 'flower'. Common, proper, abstract and collective nouns can all have plural forms. A collective noun is a singular (not plural) noun that represents a 'group' of things. For example, 'herd' is a collective noun for animals such as sheep and cows. Collective nouns can have plural forms; for example, 'herds' is the plural form of 'herd'.
"Have not been" is used with plural subjects (e.g., they, we) or with the pronoun "I," while "has not been" is used with singular subjects (e.g., he, she, it). For example, "They have not been to the store" versus "She has not been to the store."
"Has" is the singular form of the verb "have," used with third person singular subjects (he, she, it). "Have" is the plural form, used with first person singular (I), second person (you), and all plural subjects (we, they).
