Etymology: "Nattery" is simply "natter" with the adjective-forming suffix "-y" attached, so it describes someone who is given to natter. "Natter" itself is a word for idle, chatty talk, though its sense has drifted toward the grumbling, carping talk the meaning above describes. The suffix "-y" turns a noun into an adjective meaning "having the quality of" or "characterized by," so "nattery" means "full of natter."
