bieasy had to have been taught about
to need, to dare and used.
According to books these are the
semi-modals.
Also riverkid after you counted up modals must, can, could will etc..you mentioned
must, have to,
ought to etc which are not semi modals but
phrasal modals, I think.
Instead of modals, phrasal modals can be used such as
are able to (instead of modal
can)
were able to (could)
have to (instead of must),( maybe not exactly but pretty close to must)
etc..
There are also complex modals such as
may have gone
shouldn't have gone
must have been thinking
can not be solved (out)
should be considered
could have been seen (on here)
etc..
I'll tell you what? I am going to learn more about complex modals tomorrow.

hopefully this was useful for bieasy. Anyway he asked a list of the semi-modals only and not an explanation about them.
Anyway in a short time I am off on here and not be back for a few days.
