Present small in size: a foot? (8,6)
I believe the answer is:
stocking filler
'present' is the definition.
(I've seen this before)
'small in size a foot?' is the wordplay.
I cannot really see how this works, but
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is present in the answer.
'in' is within the answer.
'size' could be 'l' (large clothing size) and 'l' is found in the answer.
'foot?' could be 'f' (abbreviation) and 'f' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for stocking filler that I've seen before include "Pin, for girl, might be" , "small Christmas gift" , "Little present" , "Extra Christmas present" , "small gift at the present time" .)
