A complex sentence must have a principal clause and one or more subordinate clauses. The subordinate clause may be a noun clause, an adjective clause or an adverb clause.
We can form a complex sentence by combining two simple sentences using a subordinating conjunction like when, as, since, till, where, if, though, unless, that, lest, weather, whereas etc.
