Long to get the amount of pay you deserve (5)
I believe the answer is:
yearn
'long' is the definition.
(synonyms)
'get the amount of pay you deserve' is the wordplay.
'get' means one lot of letters go next to another.
'the amount of pay you' becomes 'y' (I am not sure about this - if you are sure you should believe this answer much more).
'deserve' becomes 'earn' (I've seen this before).
'y' next to 'earn' is 'YEARN'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for yearn that I've seen before include "Mark of injury" , "Hanker" , "Pant - pine" , "Have a craving" , "Desire strongly" .)
