Question

Identify the use of the italicized noun clause.

I found ( what I was looking for) in my purse.

(A) subject complement
(B) direct object
(C) subject

Answer 1

The italicized noun clause is used as B. direct object in this sentence.
It is relatively easy to spot a direct object in a sentence - just ask the question what/whom? So - What did I find? - What I was looking for.
There is no subject complement here, and the subject is the pronoun I.
