Where shoes may have to be removed, socks protecting you? (5)
I believe the answer is:
house
'where shoes may have to be removed' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'socks protecting you?' is the wordplay.
'socks' becomes 'hose' (I've seen this before).
'protecting' means one lot of letters goes inside another (inserted letters are held or protected).
'hose' going around 'u' is 'HOUSE'.
Can you help me to learn more?
(Other definitions for house that I've seen before include "Residence; legislative meeting-place" , "Firm; home" , "Residential building" , "Domicile" , "Dwelling, living quarters (5)" .)
