Hit on the foot? (4)
I believe the answer is:
sock
This clue could be a double definition.
'hit' is the first definition.
(socking is a kind of hitting)
'the foot' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
I also know that 'foot' relates to this answer.
'on' is the link.
Can you help me to learn more?
(Other definitions for sock that I've seen before include "Item of footwear" , "bash" , "Hit hard - footwear" , "This partly protects member" , "one with wind" .)
