Get in a stew (4)
I believe the answer is:
fret
'get in a stew' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for fret that I've seen before include "Worry - bar on the fingerboard of a stringed instrument" , "Rub - a bit of the guitar" , "Be anxious; ornament" , "Show anxiety" , "ridge > that obscures sea view" .)
