Short leg struck mid-off! (9)
I believe the answer is:
drumstick
'short leg' is the definition.
'drumstick' can be an answer for 'leg' (thesaurus). I'm unsure of the 'short' bit.
'struck mid-off' is the wordplay.
'off' indicates anagramming the letters.
'struck'+'mid'='struckmid'
'struckmid' anagrammed gives 'DRUMSTICK'.
Can you help me to learn more?
(Other definitions for drumstick that I've seen before include "Tibia of dressed fowl" , "Chicken leg (for a percussionist?)" , "a bit of leg?" , "sometimes used in a roll" , "piece of chicken?" .)
