It evidently has hot and cold running water (5)
I believe the answer is:
house
'it evidently' is the definition.
The definition suggests a singular noun which matches the answer.
'hot and cold running water' is the wordplay.
'hot' becomes 'h' (abbreviation, eg on taps).
'and' means one lot of letters go next to another.
'cold running water' becomes 'ouse' (I can't justify this - if you can you should believe this answer much more).
'h'+'ouse'='HOUSE'
'has' acts as a link.
Can you help me to learn more?
(Other definitions for house that I've seen before include "See 1" , "Accommodate" , "Domicile" , "Dwelling-place" , "Dwelling; dynasty" .)
