Final answer:
The noun 'earring' is paired with the verb 'put on' to create the noun-verb pair. The verb 'put on' changes to 'put on earrings' when referring to the past tense as it typically relates to the action performed on the pair. Subject-verb agreement is crucial for creating grammatically correct sentences and varies based on the subjects and their connectors.
Step-by-step explanation:
When considering whether 'Earring, put-on-earring' is a noun-verb pair, we first need to identify what a noun and a verb are. A noun is a word that names a person, place, thing, or idea, while a verb expresses action or a state of being. In this example, 'earring' is indeed a noun since it names an object. However, 'put-on-earring' is not a standard verb form; it seems to be a phrase describing an action. The verb form we're looking for in this case to describe the action would simply be 'put on' (without 'earring'), making 'put on' the verb that pairs with the noun 'earring'.
Furthermore, to use this pair in the past tense, we would say 'put on earring' in the present tense changes to 'put on earrings' for past tense reference since when speaking about the action in the past, it's common to refer to the pair of earrings.
In relation to subject-verb agreement and verb forms, it is important to understand that the verb must agree in number and person with its subject. For plural subjects joined by 'and', such as 'basketball and wrestling', a plural verb is used: 'are'. However, subjects that form a single idea like 'Red beans and rice' take a singular verb: 'is'. Even with compound subjects joined by 'or' or 'nor', the verb should agree with the part of the subject closest to it, whether it is singular or plural.
With singular indefinite pronouns, a singular verb is used, as most indefinite pronouns require a singular verb, but there are exceptions. Phrases functioning as subjects and subject-verb agreement rules are also crucial to constructing correct sentences.
