Subject-verb agreement means that the subject of a sentence and the verb must agree in number. This means that if the subject is singular (one), the verb must be singular, and if the subject is plural (more than one), the verb must be plural.
In the sentence you provided: Each of cakes need to be decorated, there is an error in verb form due to misunderstanding the subject.
Let's break it down:
- Identify the subject: In this case, the subject is Each. “Each” is a singular subject, despite it referring to multiple cakes.
- Determine the correct verb: Since “Each” is singular, we should use the singular form of the verb. Instead of need, we should use needs.
- Formulate the correct sentence: The corrected sentence should read: Each of the cakes needs to be decorated.
Now our new sentence correctly follows the rules of subject-verb agreement!
