Hang around wife with little energy still (7)
I believe the answer is:
however
'still' is the definition.
(I know that still can be written as however)
'hang around wife with little energy' is the wordplay.
'hang' becomes 'hover' (I've seen this before).
'around' indicates putting letters inside.
'wife' becomes 'w' (abbreviation).
'with' means one lot of letters go next to another.
'little' says to take the initial letters.
The first letter of 'energy' is 'e'.
'w'+'e'='we'
'hover' enclosing 'we' is 'HOWEVER'.
(Other definitions for however that I've seen before include "at the same time" , "at all events" , "Nonetheless" , "Though" , "On the other hand" .)
