Suitable footwear for one who can't keep their feet? (7)
I believe the answer is:
slipper
This clue could be a double definition.
'suitable footwear' is the first definition.
'slipper' can be an answer for 'footwear' (slipper is a kind of footwear). I am not certain of the 'suitable' bit.
'one who can't keep their feet?' is the second definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for slipper that I've seen before include "Footwear item" , "House shoe" , "Beat; mule" , "Comfortable shoe" , "Shoe worn indoors" .)
