a. A clause introduced by a Relative Pronoun or Relative Adverb is called a Relative Clause: -
For Relative Pronouns (or Relative Adverbs) serving to connect independent sentences, see § 308. f.
b. A clause introduced by an Adverb of Time is called a Temporal Clause: -
c. A clause containing a Condition, introduced by sí, if (or some equivalent expression), is called a Conditional Clause. A sentence containing a conditional clause is called a Conditional Sentence.
Thus, sí aquam gelidam biberint, prímó relevárí videntur (in b, above) is a Conditional Sentence, and sí ... biberint is a Conditional Clause.
d. A clause expressing the Purpose of an action is called a Final Clause: -
e. A clause expressing the Result of an action is called a Consecutive Clause: - [Observe that the classes defined in a - e are not mutually exclusive, but that a single clause may belong to several of them at once. Thus a relative clause is usually subordinate, and may be at the same time temporal or conditional; and subordinate clauses may be coördinate with each other.]
