Where to find a sole less than twelve inches long (9)
I believe the answer is:
underfoot
'where' is the definition.
Both the answer and definition are adverbs. Maybe there's an association between them I don't understand?
'a sole less than twelve inches long' is the wordplay.
I cannot really see how this works, but
'less' could be 'under' (I've seen this in other clues) and 'under' is located in the answer.
'twelve inches' could be 'foot' (I've seen this before) and 'foot' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'to find' acts as a link.
Can you help me to learn more?
(Other definitions for underfoot that I've seen before include "Little babies often are" , "on the ground" , "How things are trodden" .)
