Anger from sticky situation trapped by credit (6)
I believe the answer is:
choler
'anger' is the definition.
('choler' can be a synonym of 'anger')
'sticky situation trapped by credit' is the wordplay.
'sticky situation' becomes 'hole' (both can mean a difficult situation).
'trapped by' means one lot of letters goes inside another.
'credit' becomes 'cr'.
'hole' going inside 'cr' is 'CHOLER'.
'from' acts as a link.
(Other definitions for choler that I've seen before include "Bile, bad temper" , "Ire" , "Irritability, anger" , "ill-humour" , "bad humour" .)
