They will transfer asset to next survivor in the end (9)
I believe the answer is:
testators
'they will' is the definition.
Although both the answer and 'will' are nouns, they are not in the same form of the noun.
'transfer asset to next survivor in the end' is the wordplay.
'transfer' indicates anagramming the letters (I've seen this in other clues).
'in the end' says to take the final letters.
The final letters of 'next survivor' are 'tr'.
'asset'+'to'+'tr'='assettotr'
'assettotr' with letters rearranged gives 'TESTATORS'.
Can you help me to learn more?
(Other definitions for testators that I've seen before include "People willing" , "People who have made wills" .)
