Uncomfortable, being unable to receive visitors? (3,2,4)
I believe the answer is:
not at home
'uncomfortable' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'unable to receive visitors?' is the wordplay.
I cannot quite understand how this works, but
'unable to' could be 'no' (I've seen this in other clues) and 'no' is found in the answer.
This explanation may well be incorrect...
'being' acts as a link.
Can you help me to learn more?
(Other definitions for not at home that I've seen before include "Ignoring visitors" , "barking at the moon" .)
