153. The compound tenses formed by combining the future active
participle with each of the three aoristic tenses of "esti" represent
an act or state as about to occur in the present, past, or future,
respectively, and are called "periphrastic future tenses." Except when
great accuracy is desired, these tenses are not often used. A synopsis
of "vidi" in the first person singular and plural of these tenses is as
follows:
Present Periphrastic Future.
mi estas vidonta, ni estas vidontaj,
I am about to (going we are about to (going
to) see. to) see.
Past Periphrastic Future.
mi estis vidonta, ni estis vidontaj,
I was about to (going we were about to (going
to) see. to) see.
Future Periphrastic Future.
mi estos vidonta, ni estos vidontaj,
I shall be about to (going we shall be about to (going
to) see. to) see.
