Question

Is “we have to pretend as though we have forgotten to bring out tools today” an reletive clause

Answer 1

No, the sentence "we have to pretend as though we have forgotten to bring our tools today" is not a relative clause. It is a complex sentence with a main clause ("we have to pretend") and a subordinate clause ("as though we have forgotten to bring our tools today"). The subordinate clause functions as an adverbial clause, providing more information about the main clause.
