Maybe for you, but not for me ;-)
"Thyristor" is more of a generic term
that can include
TRIACs, DIACs, SIDACs, LASCRs, and all manner of other 4-layer
devices.
No! A thyristor is a semiconductor version of a thyratron. A triac is
something different and has *never* been called a thyristor even
though it may be seen as two anti-parallel thyristors (which is not
correct).
Yes! It appears that some people on this list call a Triac a thyristor,
and it's in use elsewhere too:
