There is no way to tell which verbs take which auxiliary.

Many verbs can take objects or complements, but nouns cannot.

In English, ordinary verbs take the auxiliary do when negated by not.

Many verbs take either and have little difference in meaning.

Other times, just the verb will take the suffix.

In addition verbs often take meaning of more perfect action when a prefix added.

The second verb can also take its own arguments, making this construction a way of connecting entire clauses.

Both nouns and verbs can take a large number of suffixes.

In many languages, the verb takes a form dependent on this person and whether it is singular or plural.

Some verbs can take any or none of these prefixes.
