Increased alarm as terms of banks never change (5)
I believe the answer is:
risen
'increased' is the definition.
(rising is a kind of increasing)
'alarm as terms of banks never change' is the wordplay.
I cannot really understand how this works, but
'change' could be 'rise' (rising is a kind of changing) and 'rise' is present in the answer.
A single letter 'n' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for risen that I've seen before include "Resin (anag.)" , "Increased" , "Ascended - restored from death" , "Grown up" , "Out of bed" .)
