Words clause and brought have similar spelling: clause is spelled 'klawz', and brought is spelled 'brawt'. So, both are spelled with 'aw'. On the other hand, their meaning is different. Also, clause is a noun while brought is a verb. A clause is a syntactic construction that forms part of a sentence or is a whole simple sentence. Brought is simple past tense and past participle of 'bring'.
