That's a matter of opinion - many linguists would say that English has
only two tenses: present and past. The rest is done with modal verbs
(e.g. "will") and aspect (e.g. perfective). If you look at English
"tenses" as combinations of tense and aspect, the Lojban way of doing
things seems a little less strange.
Yes. And much more systematic.
Thanks for this info, anyway.
I've heard that every (*every*!) language has past tense. Which is a bit
surprising if You think of that not all of them break up to words. (Some
really weird langs consist of elements that sign almost whole sentences.)
