What would be season as in "I season the meat with spices?"
Blaistigh, Leasaigh, Cuir dea-bhlas ar -
e.g. Blaistím an fheoil le spiosra.
I hear "shay-thoor!"
So do I!
Would it be the same word to note the passage of autumn and winter, to say "I season my food."
No. One way of saying "to season" would be the verb blaistigh - literally, "to add flavour".
