Here's the sentence:

Jack hopes to join the Army next month.

Answer: an infinitive phrase used as a direct object.

I defined it as: an adverb infinitive phrase used to modify the verb "hope".

I see the verb "hope' as an intransitive verb. From what I learned, an intransitive verb doesn't have a direct object to recieve the action of the verb, rather it's used, for example, with prepostions to connect with the other parts of a sentence, exmaple:

He waited for her for a long time.


He waited her a long time.

As it is with "hope":

He hopes for the best result. (intransitive verb. for the best result modifying the verb "hopes" telling how)


He hopes the best result. (the best result being the direct objective)

Would someone clarify this? Either there's misinformation in the grammar book or I was mistaken somewhere along the way? Thanks.

A phone conversation:
A: I hope...(trails off)
B: What do you hope?
A: I hope to see you soon!

B did not say "How do you hope?" B said "What do you hope?"

It requires an object - it's not an intransitive verb in this case. So the infinitive is a noun phrase, and is the direct object of hope. It is what is hoped for.

Does that make any sense?

A: I saw him trying...
B: What did you see him trying to do?
A: I saw him desperately (how he was trying) trying to open the trunk (what he was trying to do).
Within 2 minutes of the previous post, I ran into this one:

I saw him trying to open the trunk.


trying to open the trunk is a participial phrase modifying the direct object him/to open the trunk is a noun infinitive phrase used as the direct object to the verbal trying

I have no problem with the first part of the answer, but can someone explain the 2nd part?

For this one, my answer is in accordance with the grammar book's:

Jim loves to play basketball.

Answer: to play basketball is a noun infinitive phrase used as the direct object

Thank you GG, it's sinking in.

I have always thought one of the "characteristics" of an intransitive verb is that it have no direct object recieving the action of the verb because it's "intercepted" by a preposition or an infinitive "to". Wrong definition/concept then..........Emotion: sad

Thank you so much.

The infinitive also can be considered as a adverbial modifier in "I hope to see you soon", right?
