Stocking fillers on front of sleigh (4)
I believe the answer is:
legs
'stocking fillers' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps you can see an association between them that I don't see?
'on front of sleigh' is the wordplay.
'on' becomes 'leg' (cricket term, fielding positions).
'front of' indicates taking the first letters (the letter at the front of the word).
The initial letter of 'sleigh' is 's'.
'leg'+'s'='LEGS'
Can you help me to learn more?
(Other definitions for legs that I've seen before include "Sections of a journey or course" , "Lower limbs" , "Members" , "associated with 11 in game" , "Stages of a journey" .)
