Coin stuck in meter provoked anger (8)
I believe the answer is:
embitter
'anger' is the definition.
(I know that anger can be written as embitter)
'coin stuck in meter provoked' is the wordplay.
'coin' becomes 'bit' (term for various historical coins).
'stuck in' means one lot of letters goes inside another.
'provoked' indicates anagramming the letters.
'meter' with letters rearranged gives 'emter'.
'bit' going inside 'emter' is 'EMBITTER'.
(Other definitions for embitter that I've seen before include "Infect with ill-feeling or resentment" , "Make resentful or disillusioned" , "Create resentment" , "Make sour and resentful" , "poison" .)
