I promised a follow-up with infinitives, so here it is!
The next thing to lean is infinitive phrases. Infinitive phrases are groups of words consisting of an infinitive and a modifier and/or (pro)noun(s) or noun phrase(s) that function as the actor(s), direct object(s), indirect object(s), or complement(s) of the action or state expressed in the infinitive such as;
We intended to leave early.
(to leave is the infinitive)
(early is the adverb)
*The infinitive phrase functions as the direct object of the verb intended.
Another example is the below.
Phil agreed to give me A RIDE.
(to give is the infinitive)
(me is the indirect object of action expressed in infinitive)
(A RIDE is the direct object of action expressed in infinitive)
*The infinitive phrase functions as the direct object of the verb agreed.
There are also three points to remember when going through this process:
1) An infinitive is a verbal consisting of the word to plus a verb; it may be used as a noun, adjective, or adverb.
2) An infinitive phrase consists of an infinitive plus modifier(s), object(s), complement(s), and/or actor(s).
3) An infinitive phrase requires a comma only if it is used as an adverb at the beginning of a sentence.
