I'm a little stuck... Click here to teach me more about this clue!

'farmer' is the definition.
(Farmer Giles is a stereotypical name for a farmer)

(Other definitions for giles that I've seen before include "Carl _____, newspaper cartoonist" , "Farmer --- of Ham (Tolkien)" , "Boy's name" , "Sir - Gilbert Scott, English architect" , "-- Coren; -- Brandreth" .)
