Clauses of prevention
This chapter describes the subjunctive used in an array of situations, both in dependent clauses such as purpose and result clauses and in independent clauses such as wishes and negative commands. There is a few related situations in which it is not as readily evident semantically why the subjunctive has come into use. Latin subordinate clauses which are dependent on certain types of other clauses may take their verbs in the subjunctive. The two main instances of this are when dominating the verb is a subjunctive itself and an infinitive. In addition to being dependent upon a subjunctive verb or an infinitive, the attracted verb is an essential or integral part of the thought of the clause upon which it depends. While such an essential or integral semantic value is often noticeable, it is far from being consistently palpable, especially in an English translation.
