He follows Nick, losing task finally: a comfortable position (5)
I believe the answer is:
niche
'a comfortable position' is the definition.
(I've seen this before)
'he follows nick losing task finally' is the wordplay.
I cannot quite see how this works, but
'he' could be 'che' and 'che' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for niche that I've seen before include "Recess - suitable position" , "Cosy spot" , "A small recess or easy job" , "small specialised market" , "Suitable slot" .)
