10.04.26: Level 3; Subjunctive [15] independent uses [3] deliberative [i]

From deliberō, -āre [1]: consider carefully; deliberate.
When we say, “What am I (supposed) to do?” or “What should / ought I to do?”, we are deliberating — that is, we express doubt or uncertainty about the correct course of action. The speaker may be addressing him- or herself, genuinely asking for guidance, or framing a rhetorical question (e.g. “What am I supposed to do?”). In Latin this kind of deliberation is expressed by the subjunctive.

Indicative: Quid facimus? │ What are we doing?

Subjunctive: Quid faciāmus? │ What are we to do / should we do?

Quid dīcam? │ What am I to say?

Quid faciam? │ What am I to do?

Huic cēdāmus! hūius condiciōnēs audiāmus! (Cicero)│ Are we to bow to him! Are we to listen to his terms!

Quid agam, iūdicēs? Quō mē vertam? (Cicero) │ What am I to do, judges? Where am I to turn to?

Etiamne eam salūtem? (Plautus) │ Am I to greet her?

Quid hōc homine faciās? Quod supplicium dīgnum libīdinī eius inveniās? │ What are you to do with this man? What fit penalty can you devise [lit: are you to find] for his wantonness?

The negative deliberative is constructed with nōn:

Hunc ego nōn dīligam? (Cicero) │ Should I not cherish this man?
