Subordinate Clause:
A subordinate clause, like an independent clause, has a subject and a verb, but unlike an independent clause, it cannot stand alone as a sentence.
Subordinate clauses begin with certain words or short phrases called subordinating words.
It is a clause that does not form a simple sentence by itself and that is connected to the main clause of a sentence In the sentence "I went home because I felt ill," "because I felt ill" is a subordinate clause.
Sentences with two subordinate clauses occur quite of- ten in corpora. Theories and tools in Computational Lin- Guistics are available now which allow us to study such sentences exhaustively, both at the syntactic and semantic level.
