Pleasant to put husband in recess (5)
I believe the answer is:
niche
'recess' is the definition.
(I know that recess can be written as niche)
'pleasant to put husband in' is the wordplay.
'pleasant' becomes 'nice' (similar in meaning).
'to put husband' becomes 'h' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in' means one lot of letters goes inside another.
'nice' placed around 'h' is 'NICHE'.
Can you help me to learn more?
(Other definitions for niche that I've seen before include "Specialist area" , "Small corner of e.g. market" , "Select place in market" , "Recess - suitable position" , "Place that's cosy" .)
