Yes, I'm in the same chapter.
has already been done to the present stem to obtain the imperfect.
But still, they are slightly different, especially the 3rd and 4th conjugation... And the participles match pefectly with the imperfect right down to vowel length when dropping the bam, bas, bat, etc. I was wondering about more about the direct connection and not really about the indirect connection (i.e. imperfect from perfect).
Using the imperfect stem: I got that idea from a book called "Latin in 24 hours". Hehehe.
The future passive participle is the gerundive (i.e., the same form of verbal adjective is used as a future passive participle and for various other "gerundive" uses, such as expressing purpose or obligation in certain constructions.)
Well... the definition was kind of awkward in it's wording. I first got the impression that since gerundive functions as a future passive participle in other cases
that meant that it isn't a future passive particple in the nominative case... but oh well... lexicography...
