What is the Latin for 'answering an unasked question'?

Answer 1

The second conjugation verb respondēre means "to answer, to reply." The principal parts are respondeō, respondēre, respondī, respōnsum. onjugated forms would vary depending on what exactly is the subject, and what exactly is doing the answering (or being answered if in the passive voice.)

The second declension, neuter noun responsum, responsimeans "answer, reply, response."

Answer 2

The Latin equivalent of 'answering an unasked question' is Respondere qaestionem non rogatam. In the word-by-word translation, the infinitive form of the verb 'respondere' means 'answering' in its use as a substitute for the gerund nominative. The noun 'quaestionem' is the feminine form of the accusative case, and means 'question'. The adverb 'non' means 'not'. The adjective 'rogatam' is the feminine form that agrees with its noun, 'quaetionem'; and means 'asked'.

Answer 3

"Answer" as a noun is responsio, responsum or explicatio.

As a verb, "I answer" is respondeo, rescribo, praesto.
