THE MEANINGS OF SUBORDINATE CLAUSES

393. Subordinate clauses may be classified not only according to their use as parts of speech, but also, in quite a different way, in accordance with their various meanings. These distinctions in idea are of capital importance for the accurate and forcible expression of thought.
