Feeling low having been kicked out after a day (8)
I believe the answer is:
dejected
'feeling low' is the definition.
(thesaurus)
'kicked out after a day' is the wordplay.
'kicked out' becomes 'ejected' ('eject' can be a synonym of 'kick out').
'after' means one lot of letters go next to another.
'a day' becomes 'd' (abbreviation for day).
'ejected' after 'd' is 'DEJECTED'.
'having been' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for dejected that I've seen before include "Melancholy" , "Down in the mouth" , "Downcast" , "Despondent" , "Downhearted" .)
