For tenses, other than ZAhO, the selbri is expressly not limited to the tensed part of it. Thus "ba" means that the selbri will hold at some point in the future - it says nothing about how often or over how long an interval, nor whether it has held in the past or does so now. As I understand it, even using ZEhA and VEhA this is true: "mi baze'u gleki" says that there is an long period at least partly in the future over which I will be happy - it does not rule out my happiness in the past, nor disjoint periods of happiness in past, present and future. Even "mi canaijebaze'uca gleki" which says that I am not happy now but will be over a long period in the future starting now, does not say anything about the past, or about times even further in the future. The one set of expressions which by definition express limitations on the temporal or spatial extent of a bridi is ZAhO. Even there, not all do: "ca'o" for example says that I am at a point within the bridi - not at the beginning or the end. I presume that mi caze'aca'o gleki means that I am currently experiencing a medium-length period of happiness within a longer span (though it may be only very slightly longer). In fact the hard thing seems to me to be delimiting the bridi precisely. It may be that this is what "co'i" does, but I'm not sure. So turning to your examples: - perfective: 'he lived for only 20 yrs' ko'a (pu)co'i nanca li reno (???) - imperfective-A: 'he lived for at least 20 yrs' ko'a (pu)nanca li (su'o)reno - imperfective-B+perfective: 'he is in the middle of a life of 20 years' duration' ko'a (ca)ca'o nanca li (su'o)reno - imperfective-B+imperfective-A: 'he is in the middle of a 20-year portion of his life' ko'a (ca)ca'oca'o nanca li su'oreno (??? It's grammatical, but is this what it means?) Does this answer your question? Colin
