THE SUBJUNCTIVE OF PURPOSE
348. Observe the sentence
Caesar hominēs mittit quī pontem reperiant,
Cæsar sends men to find the bridge
The verb reperiant in the dependent clause is in the subjunctive because it tells us what Cæsar wants the men to do; in other words, it expresses his will and the purpose in his mind. Such a use of the subjunctive is called the subjunctive of purpose. 349. Rule. Subjunctive of Purpose. The subjunctive is used in a dependent clause to express the purpose of the action in the principal clause.
350. A clause of purpose is introduced as follows: I.If something is wanted, by
quī, the relative pronoun (as above)
ut, conj., in order that, that
quō (abl. of quī, by which), in order that, that, used when the purpose clause contains a comparative. The ablative quō expresses the measure of difference. (Cf. § 317.)
II.If something is not wanted, by
nē, conj., in order that not, that not, lest
Caesar cōpiās cōgit quibus hostīs īnsequātur
Cæsar collects troops with which to pursue the foe
Pācem petunt ut domum revertantur
They ask for peace in order that they may return home
Pontem faciunt quō facilius oppidum capiant
They build a bridge that they may take the town more easily (lit. by which the more easily)
Fugiunt nē vulnerentur
They flee that they may not (or lest they) be wounded
352. Expression of Purpose in English. In English, purpose clauses are sometimes introduced by that or in order that, but much more frequently purpose is expressed in English by the infinitive, as We eat to live, She stoops to conquer. In Latin prose, on the other hand, purpose is never expressed by the infinitive. Be on your guard and do not let the English idiom betray you into this error.
