Learnt to change hire deal (6)
I believe the answer is:
rental
'hire deal' is the definition.
'rental' can be an answer for 'hire' (I've seen this before). I'm not sure about the 'deal' bit.
'learnt to change' is the wordplay.
'to change' indicates anagramming the letters.
'learnt' with letters rearranged gives 'RENTAL'.
Can you help me to learn more?
(Other definitions for rental that I've seen before include "Learnt (anag) -- lease" , "To do with a letting" , "Money paid for hire" , "4 across (anag)" , "Charge to hirer" .)
