Feeling out of sorts in your armchair and uncomfortable? (3,2,4)
I believe the answer is:
ill at ease
'uncomfortable?' is the definition.
(being ill at ease is being uncomfortable or uneasy)
'feeling out of sorts in your armchair' is the wordplay.
I cannot quite understand how this works, but
'out of sorts' could be 'ill' (I've seen this before) and 'ill' is found within the answer.
The remaining letters 'atease' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for ill at ease that I've seen before include "Unable to relax" , "Elite, alas? (Anag)" , "Fidgety" , "Nervous, uncomfortable" , "Unsure and constrained in manner" .)
