Conditional Clauscs.

317. A conditional clause is an antecedent to some effect or event, but not necessarily its cause.

318. Conditional clauses are used to limit the principal clause by means of some real or supposed condition; as, If it rains, I shall not go."

319. When the conditional clause denotes something actual, or assumed as actual, the terise form of the verb indicates its true time; as, “ If it rains, raincd, or has rained, I shall not go.”

320. When the conditional clause denotes something supposed or hypothetical, the tense form of the verb does not indicate its true tine.

(a.) The past tense represents present time; the past perfect, past time; and the past of the potential, future time; as, “ I am not going; but if I were going (now), I should ride ;" “ I was not going; but if I had been going (yesterday), I should have told you;

“I shall not go; but if I should go (hereafter), I should walk."

(6.) Sometimes there is an ellipsis of the auxiliary ; as, “If ho thould) come, we will ride into the country."

321. The principal connective of conditional clauses is if. The following, which may be con

sidered as nearly equivalent to if, are also used :unless (if not), though, lest, except, provided that.

322. The verb of the conditional clause is in the subjunctive mode, and may be either of the indicative or potential form, (86;) that of the principal clause is generally either in the indicative future, or in some tense of the potential.

323. Conditional clauses may become principal clauses, by changing the subjunctive to the imperative mode, and using and instead of if; as, " If you will give me an are, I will cut this tree" =“Give me an axe, and I will cut this tree."

(a.) Sometimes the condition is expressed by a question; as, " Is any among you afflicted ? let him pray”="If any (one) among you is afflicted, let him pray.”

(b.) By placing the subject after the verb, or between the auxiliary and the verb, “if" may be omitted ; as, “ Weie he a more mareful man, he would meet with better success."

EXERCISE 51.

Analyze the following complex sentences, and parse the connectives :

If a tree loses its leaves before the fruit is ripe, the latter becomes withered. If the bark of a tree is injured, the tree becomes sick, and finally dies. Except ye repent, ye shall all likewise perish. If you will read my story, you can judge for yourself. If you would enjoy health, bathe often. I shall leave to-morrow,

unless

my

friend arrives. You may return, if you please. Should it rain to-morrow, (323, b.) the lecture will be postponed. Were the cause good, he would not fear the attack of its enemies. Were patrons more disinterested, ingratitude would be more rare

wish to cut glass, we must have recourse to the diamond, Had I acted from personal enmity, I should justly be despised. If there be any thing improper in this address, the singularity of your present situation will excuse it.

MODEL. If you leave, no one can supply your place.

Final Clauses.

324. Clauses which denote a purpose, or motive. are called final clauses. They are connected by that, that not, and lest.

(a.) Lest denotes a negative purpose, or the avoidance of an ovil, and is nearly equivalent to that not ; as, “ Take heed lest ye fall=thar ye do not fall.

325. The potential mcde, or subjunctive, potential form, is always emple yed in final clauses, and the imperative or potential is commonly used in the principal clause.

326 An adjective clause, introduced by a preposition, and having its ierb in the potential mode, generally denotes a purpose ; as, “We have no other means by which we may aid him.

(a.) Final clauses are often equivalent to an infinitive; as, Eat that you may

live “ Eat to live." (b.) Final clauses generally relate to some correlative phrase in the principal clause, such as, “ in order," " with the design."

EXERCISE 52.

Adversative Clauses.

327. Adversative clauses are used when we concede something which stands as a cause or reason opposed to the statement in the principal clause. They are introduced by though, although, notwithstanding, however; as, “ Though he slay me, yet will I trust in him."

(a.) The correlatives of adversative clauses are, yet, still, or nevertheless, placed in the principal clause.

(6.) Whatever, whoever, whichever, and while, often have an adversative signification; as, “ Whatever you may say, sists in doing it.”

328. An adversative clause may be expressed by a comparison of equality; as, “Poor as he was, he contributed more than any other man 'Though he was poor, he contributed more than Any other man."
