the cat-PAST eat-PREDICTIVE the mouse-PAST = the cat was going to eat the mouse
the cat-PRESENT eat-IMPERFECT the mouse-PRESENT = the cat eats the mouse
the cat-FUTURE eat-PERFECT the mouse-FUTURE = the mouse will have eaten the mouse
Someone on the list however (sorry, I can't remember who), suggested having the tense marking on the object be relative to the subject. In that way, tense and aspect could both be covered by the nouns. (past object = perfect aspect, present object = imperfect aspect, future object = predictive aspect).
the cat-PAST eat the mouse-FUTURE = the cat was going to eat the mouse
the cat-PRESENT eat the mouse-PRESENT = the cat eats the mouse
the cat-FUTURE eat the mouse-PAST = the cat will have eaten the mouse
I like this system because it's simple and elegant, yet allows for a pretty wide range of meanings, so I think it will be pretty useful, and also because it frees up the verb, so to speak, so I can do something else with it. More on that in my next post.
