§443. Subjunctive Mood

The Subjunctive was used in sentences of interrogative form, at first when the speaker wished information in regard to the will or desire of the person addressed. The mood was therefore hortatory in origin. But such questions when addressed by the speaker to himself, as if asking his own advice, become deliberative or, not infrequently, merely exclamatory. In such cases the mood often approaches the meaning of the Potential (see § 445). In these uses the subjunctive is often called Deliberative or Dubitative.
