Mood and viewpoint
Choose mood and subordinate tense from stance and time.
Certainty, doubt, and reported perception
Sapeva che and constatò che normally introduce a stated fact with the indicative: Paolo sapeva che il rapporto indicava un giunto allentato. Temeva che, dubitava che, and sembrava che present fear, doubt, or appearance and take the subjunctive. With a past main verb, use imperfetto congiuntivo for a simultaneous or later situation (temeva che il ponte cedesse) and trapassato congiuntivo for a prior situation (temeva che il ponte avesse già ceduto). The speaker’s stance does not make a feared event true.
- Paolo sapeva che il rapporto indicava un giunto allentato.· Paolo knew the report indicated a loose joint.
- Marta temeva che il ponte cedesse.· Marta feared the bridge might give way.
- Marta dubitava che il Comune avesse già deciso.· Marta doubted that the municipality had already decided.
- A Elena sembrava che i ricordi fossero meno precisi degli orari.· It seemed to Elena that the memories were less precise than the times.
Shift the reference time without changing the evidence
With a present main verb, use present subjunctive for a current or later uncertain event (temo che il ponte ceda) and past subjunctive for a prior uncertain event (dubito che sia crollato). With a past main verb, shift to imperfect or pluperfect subjunctive. Compare what a witness thought in 1998 with what an archivist can say now. Nonostante takes the subjunctive in a concessive clause even when the fact is accepted: nonostante il rapporto fosse chiaro, Marta aveva paura. Do not choose mood by a single English translation; identify the Italian trigger and time relation.
- Temo che il ponte ceda.· I fear the bridge may give way.
- Temevo che il ponte cedesse.· I feared the bridge might give way.
- Dubito che il ponte sia crollato.· I doubt the bridge collapsed.
