Question

The lady found a sweeper boy add a clause

Answer 1

In this sentence there are three finite verbs(verbs whose meaning is complete). 1. heard - Past Indefinite 2. Mention (a non used as a verb here) - Present Indefinite 3. Was in need of - a phrasal verb Simple Past tense(Past Indefinite). Thus there must be 3 Clauses. The portion of the sentence that follows the subordinating conjunction 'that' is the Subordinate Clause.

Now for the Main Clause that is marked by 'heard' ie Sitaram heard is the one. 'the lady of the house mention' is a Noun Clause that is serving as the Object of the Main Clause.

Now what remains to be fixed is whether this is a complex sentence or a compound-complex sentence. For this the relation between the MC ‘Sitaram heard' and 'the lady of the house mention' are connected by an invisible coordinating or subordinating conjuction. Since we find that that clause functions as an object of MC, this is overall a Complex Sentence.
