๐ Understanding Subject-Verb Agreement: 'And' vs. 'Or'
Subject-verb agreement means the verb in a sentence must agree in number with its subject. This can get tricky with compound subjects, where two or more subjects are joined by 'and' or 'or'. Let's break it down:
โ 'And' in Compound Subjects
Generally, when subjects are joined by 'and', they create a plural subject and require a plural verb.
- ๐จโ๐ซ Example: Tom and Mary are going to the library.
- โจ Exception: If the parts of the compound subject refer to a single thing or person, a singular verb is used.
- ๐ณ Example: Macaroni and cheese is my favorite dish. (Here, 'macaroni and cheese' is considered one dish.)
๐ค 'Or' in Compound Subjects
When subjects are joined by 'or' (or 'nor'), the verb agrees with the subject closest to the verb.
- ๐ฉโ๐ Example: The teacher or the students are going to present.
- ๐งโ๐ซ Example: The students or the teacher is going to present.
- โ๏ธ If one subject is singular and the other is plural, it's usually best to put the plural subject closer to the verb to avoid awkwardness.
