A compound verb is a multiword verb form consisting of one or more auxiliary verbs and a main verb, as in I have seen the movie, She has gone home, We will have decided this issue sometime next week.
An unfortunate—and incorrect—rule has developed among some writers: They believe that an adverb never comes between the parts of a compound verb. They are wrong. In fact, the opposite is true: The adverb should frequently come between the auxiliary and the main verb, as in should frequently come.
To put adverbs in their proper place, follow these seven conventions. The adverbs appear in bold underlined type, the verbs in bold type:
1. To stress the adverb, put it before the subject.
The teacher sometimes uses the dictionary.
3. Do not put an adverb between a verb and its object.
Avoid: I understand entirely the rule governing the placement of adverbs. (The word understand is the verb and rule is its object; no adverb should come in between.)
Instead: I entirely understand the rule governing the placement of adverbs.
