How to construct an indirect question

They are subordinate clauses which represent a question: for this reason, they are follow verbs such as quaero, rogo (= to ask) or scio (= to know).  They may be introduced by an interrogative adjective/pronoun (quis/quid or qui/quae/quod) or by small words that have to be translated as ‘if’: these words are ne, if we do not know the answer to the question, or num/none, if it is a rhetoric question. If the questions implies the choice between two alternatives, the subordinate clause is constructed with utrum .. an / -ne .. an, where an precedes the second alternative. In the indirect question we have to use the subjunctive, whose tense may vary according the tense of the verb in the main clause (consecution temporum) A) If the main clause has a verb in the present or future indicative, the subjunctive may be 1) Present if I want a contemporaneous action to the main clause’s one 2) Perfect to represent an earlier action with respect to the main clause 3) Future participle + present subjunctive of sum (= to be) for a following action compared to the main clause B) If the main clause has a verb in a past tense indicative, the subjunctive may be 1) Imperfect if I want a contemporaneous action to the main clause’s one 2) Pluperfect to represent an earlier action with respect to the main clause 3) Future participle + imperfect subjunctive of sum (= to be) for a following action compared to the main clause
