Sick of most bills being met with mere promises (7)
I believe the answer is:
bilious
'sick' is the definition.
('bilious' can be similar in meaning to 'sick')
'most bills being met with mere promises' is the wordplay.
'most' means to remove the first letter.
'bills' becomes 'ious' (I've seen this in other clues).
'being met' is a charade indicator (letters next to each other).
'with mere promises' becomes 'bili' (I can't justify this - if you can you should believe this answer much more).
'ious' with its initial letter taken off is 'ous'.
'ous' put after 'bili' is 'BILIOUS'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for bilious that I've seen before include "Nauseated; irritable" , "Affected by illness, yellowgreen?" , "Affected by illness, or just bad-tempered" , "Showing irritation" , "Feeling sick" .)
