That would look like this (you want to add the missing greek letter
names):
(defconst crucible-mtksy-keywords
`(;; Greek
(,(rx "\\" word-start
(or "alpha" "beta") ;add the other letters here
word-end)
(0 'crucible-mtksy-tfc))))
The result will be a slightly optimized regexp (equivalent to yours of
course).
If you want to go that way, I think it would also be possible to avoid
the repetition of uncapitalized followed by a capitalized letter name.
HTH,
Michael.
