200. The compound tenses formed by combining the future passive
participle with each of the three aoristic tenses of "esti" represent
an act or condition as "about to be undergone" in the present, past,
or future, respectively. These are called "passive periphrastic future
tenses". Except when great accuracy is desired, these tenses, like those
of the active voice (153) are not often used. A synopsis of "vidi" in
the first person singular of these tenses is as follows:
Present Periphrastic Future.
mi estas vidota, I am about to be (going to be) seen.
Past Periphrastic Future.
mi estis vidota, I was about to be (going to be) seen.
Future Periphrastic Future.
mi estos vidota, I shall be about to be (going to be) seen.
