Final answer:
Two-word verbs, or phrasal verbs, combine a verb and a preposition or adverb to create a new meaning, different from the original verb. Subject-verb agreement rules must be followed, with attention to compound subjects, indefinite pronouns, and phrases.
Step-by-step explanation:
Understanding Two-Word Verbs
Two-word verbs, also known as phrasal verbs, consist of a verb and a preposition or adverb that modifies or changes the meaning of the verb. The meaning of a two-word verb can be quite different from the meaning of the verb on its own. For example, 'turn down' means to refuse, whereas 'turn' can mean to rotate or change direction. A clear understanding of two-word verbs is essential for mastering English language nuances.
When considering subject-verb agreement, it is also important to note that the verb in a sentence must agree in number with its subject. For compound subjects joined by 'and', a plural verb is generally used, unless the compound subject is a singular entity. When compound subjects are connected by 'or' or 'nor', the verb should agree with the part of the subject nearest to the verb. Additionally, when the subject includes indefinite pronouns or is part of a longer phrase, singular verbs are typically used.
It is also crucial to maintain verb tense consistency throughout your sentences. Changing tenses improperly can cause confusion and make it difficult for readers to understand the timing of actions. Strengthening verbs involves removing weak, wordy phrases and choosing more direct, impactful verbs, which can make sentences clearer and more powerful.
