...alcove kind hothead put in (5)
I believe the answer is:
niche
'alcove' is the definition.
(I've seen this before)
'kind hothead put in' is the wordplay.
'kind' becomes 'nice' (I've seen this in another clue).
'hothead' becomes 'h' (head letter of 'hot').
'put in' is an insertion indicator.
'nice' going around 'h' is 'NICHE'.
(Other definitions for niche that I've seen before include "A small recess or easy job" , "Specialized market" , "Suitable position (in market, life etc)" , "comfortable situation" , "Recess; comfy corner" .)
