Wikipedia says that the word "functor" is borrowed from work by Carnap
on linguistics. Is anyone aware of other roots of category theory that
come from linguistics/semiotics?

Saunders MacLane used to tell me that it was inspired by Kant.

Yes, for sure, "category" was inspired by Aristotle and Kant.
But functor?

In Categories for the working mathematician Mac Lane
himself explains the origin of the terminology
(end of first chapter):
"Functor" is taken from
R. Carnap, Logische Syntax der Sprache (1934).
I am not sure whether linguistics/semiotics in our sense
correctly refers to Carnap
(Frege, Carnap, Goedel, Popper, Quine, Tarski, ...).
Best regards
Johannes
