Piece of meat found in small wood (5)
I believe the answer is:
steak
'piece of meat' is the definition.
(steak is a type of meat)
'small wood' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'wood' becomes 'teak' (type of timber).
's'+'teak'='STEAK'
'found in' is the link.
(Other definitions for steak that I've seen before include "Slice of meat or fish" , "Takes (anag.)" , "High-quality cut of beef" , "Thick slice of meat" , "Getting cut" .)
