Question

The grey-blue ocean stretched out before him. Identify the sentence parts?

Answer 1

The subject/topic is Ocean and the verb would be stretched.
Hope this helps! :D

Answer 2

The ocean would be the subject.

Grey-blue would be an adjective.

Stretched would be the verb.

Out would be an adverb.

Before would be a preposition,

And him would be a pronoun.

(I think before him would be the direct object, or just him)

I don't think there are any subject complements or objective complements... Or maybe I'm just stupid.
