Bring up the majority at the very end (8)
I believe the answer is:
rearmost
'the very end' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'bring up the majority' is the wordplay.
'bring up' becomes 'rear' (as in rearing children).
'the majority' becomes 'most' (most of a group).
'rear'+'most'='REARMOST'
'at' is the link.
Can you help me to learn more?
(Other definitions for rearmost that I've seen before include "Furthest back" , "More rats (anag)" , "last" , "farthest from the front" , "Fully behind" .)
