Being able to recognize the subject and the verb in a sentence will help you make sure that your own sentences are complete and clear. To check that you've included the subject and verb in your sentences, follow these steps:
Some sentences are not that cooperative about the placement of their subject and verb, however. In most sentences, the subject will come before the verb. Not so with questions. In a question, the verb often comes before the subject. Here are some examples:
To find the subject in a question, rewrite the question as a statement. The question “Is the frog in the freezer?” becomes “The frog is in the freezer.” Now the subject, frog, is in the usual position before the verb.
