Person with a will to try and toss list back (8)
I believe the answer is:
testator
'person with a will' is the definition.
(I've seen this before)
'try and toss list back' is the wordplay.
'try' becomes 'test' (synonyms).
'and' says to put letters next to each other.
'toss list' becomes 'rota' (I can't justify this - if you can you should give a lot more credence to this answer).
'back' shows that the letters should be reversed in order.
'rota' reversed gives 'ator'.
'test'+'ator'='TESTATOR'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for testator that I've seen before include "Will signatory" , "He's willing" , "One who has made will" , "one may need solicitor" , "Person who has made a will" .)
