Ah ... perhaps the easiest way is to detect recognisable suffixes on
input words, and strip them for the initial match attempt, i.e. only the
part of the word you want is hashed. A flag, or non-null
"found_this_suffix" string variable, retained from the partial-match
generating pre-stripping, then guides any additional actions, if
required.

To cover the case where a word with a recognisable suffix is in the list
with suffix, rather than without, a check-on-match-failure for the
unstripped word could be performed. It would only occur when a suffix is
detected, and would in also be faster than a search.

That essentially reverses the order of match vs suffix handling.
Speed-wise, I'd expect the pre-strip to be quite a bit faster than the
partial match, since the suffix list is unlikely to number 200,000
entries.
