What is “subject/verb agreement”?: Difference between revisions

An intervening expression is an expression that describes the subject and should not affect the verb. These expressions are often mistaken for being the subject of the sentence. Verbs are sometimes separated by words that describe the subject. This can make it difficult to make sure that the subject and verb agree. The key is to make sure that the verb agrees with the subject and not with the word in the modifying phrase. When intervening words ending in "s", such as sometimes and always, the "s" ending still must appear on a present tense verb if the subject is singular.
