Easier reproduction case:

----
(setq ispell-program-name "/usr/bin/hunspell")
(ispell-change-dictionary "en_GB")
(flyspell-mode)

etc.
----

Note red wiggle under etc.  `M-$' on the etc gives me:

So flyspell doesn't really understand that a full stop can be part of a
word, apparently?  (This is with Emacs 29.)
