Almost exploit rugby team for vast wealth (8)
I believe the answer is:
millions
'for vast wealth' is the definition.
I can't judge whether this defines the answer.
'almost exploit rugby team' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'exploit' becomes 'milk' (to milk something is to exploit its potential).
'rugby team' becomes 'lions' (British and Irish Lions).
'milk' with its last letter taken away is 'mil'.
'mil'+'lions'='MILLIONS'
Can you help me to learn more?
(Other definitions for millions that I've seen before include "Slim lino for large numbers" , "An amount this large could make Simon ill" , "fortune?" , "huge numbers" .)
