Latin Grammar: Purpose Clause
Res vero ad quas sunt corpora artificialia, sunt fines et intentiones, sicut pannus factus est ut cooperiat, et ensis ut feriat, et lectus ut nos a terra suspendat. Res vero propter quas sunt corpora artificialia sunt sicut vitrum ut in eo reponatur id quod exsiccari timetur.
The purpose clause, introduced by ut, indicates the final objective that is worked towards in the main clause. In English, purpose is usually indicated by an infinitive rather than a subordinate clause and, as such, most purpose clauses are best translated as an infinitive, or by the more formal “in order that.” The negative purpose clause is introduced by ne, and the verb of the clause is in the subjunctive mood. Practice purpose clauses by translating the following sentences into Latin.
