Regex that matches word end AND isn't a “#”
Question
My regex currently detects a "ence" suffix:
/ence\b/
However, I do not want it to match on ence# . How can I say "match on ence\\b , but that end-of-word cannot be "#"?

You may use a negative lookahead:
/ence\b(?!#)/
^^^^^
See the Rubular demo
Details :
-
ence- a literal substring -
\\b- a word boundary (since it is preceded with a word char,e, the next char must be a non-word char or end of string) -
(?!#)- the negative lookahead that fails the match if there is a#immediately to the right of the current location.
