/{2,}\w/ is not a valid regex. This is what perl will tell you
(if your regex is exactly this and there's nothing in front of it
to unintentionally precede it):
Quantifier follows nothing in regex; marked by <-- HERE in m/{
<-- HERE 2,}/ at -e line 1.
You may have meant /\w{2,}/, but that doesn't match two or more
words. It matches two or more word /characters/. For two words
you'd need something more like /\w+(\W+|$){2,}/ (of course the
definition here of "word" might not match what you're thinking
either so you should reference the docs). Another possible
interpretation might be white-space delimited, as in
/\S+(\s+|$){2,}/. Neither of these regexes have been tested for
errors.
