I thought I posted this yesterday but somehow the intertubes appear to have eaten it. I'm curious what function 'disappear' serves in this sentence. Is it a verb? Adverb modifying car? All comments are appreciated.
(2) Mr. Antonson, who has taught me so much about the Reed-Kellogg diagramming system, has given you one excellent analysis.
(3) May I give you another analysis? (You did welcome "all comments," even those from this humble soul.)
(4) I should analyze your sentence this way:
I = subject
saw = verb
the car (to) disappear. (infinitive phrase that is the object of the verb "saw.")
(a) "the car" is the subject of the infinitive "(to) disappear."
(i) One book (A Grammar of Present-Day English by Pence & Emery) explains:
The infinitive without to ... is often used in infinitive clauses following certain verbs , such as let, help, make, see, hear, etc. They give these examples:
I felt the ground shake (= I felt the ground to shake); Did you see him run away? ( = Did you see him to run away?) REMEMBER: in such sentences, native speakers do NOT say "to."
(5) Here are some more examples. (You may choose to analyze them as objective complements -- as did Mr. Antonson -- or infinitive phrase/clause as do some books):
I saw him leave.
I heard her sing.
She made me laugh.
(P.S. Those three examples come from House & Harman's wonderful Descriptive English Grammar. I wish to
emphasize that they call them "objective complements" -- as does Mr. Antonson.)
