Ch 9 · Lesson 14

Amatus sit and dixerit: passives and a lookalike

, : the participle plus the subjunctive of . And , which can be the perfect subjunctive or the future perfect: the clause decides.

The short version

Only -erim tells it from the future perfect

.

I do not know what he has done.
Why?

The perfect subjunctive is the perfect stem plus -erim, -eris, -erit, -erimus, -eritis, -erint. The future perfect is identical except for -ero in the first person singular, so can be either. Let the clause decide: a question word or points to the subjunctive.

Passive and deponent forms

Neither tense has a one-word passive. Use the participle with the subjunctive of : for the perfect, for the pluperfect.

The participle agrees with its subject, as in every perfect passive:

  • . - He asks whether the city has been captured.

Deponents use the same shape and keep their active meaning: , I followed; , he had spoken.

Perfect subjunctive or future perfect?

Only -erim against - is safe. So let the clause decide:

.I do not know what he did.
+ you .Do not do this.

has no past meaning at all: it is simply Latin's ordinary don't, beside . Do not translate it you will not have done.

Going further: Both tenses on one screen and the rest of the guide, when you want them. This lesson does not need them.
