Being so unpopular, had to get out of some hotel (5)
I believe the answer is:
hated
'being so' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'unpopular had to get out of some hotel' is the wordplay.
'unpopular' becomes 'e' (I can't explain this - if you can you should give a lot more credence to this answer).
'to get' is an insertion indicator.
'out of' indicates putting letters inside (some letters on the outside of others).
'some' indicates the central letters.
The middle of 'hotel' is 't'.
'e' placed within 'had' is 'haed'.
'haed' going around 't' is 'HATED'.
Can you help me to learn more?
(Other definitions for hated that I've seen before include "Abhorred" , "Unpopular" , "was unable to stand" , "Abominated" , "couldn't stand" .)
