Attracted many with a share of the reward (4)
I believe the answer is:
drew
'attracted' is the definition.
(I've seen this before)
'many with a share of the reward' is the wordplay.
'many' becomes 'D' (Roman numeral for 500).
'with' says to put letters next to each other.
'a share of the reward' becomes 'rew' (I can't justify this - if you can you should believe this answer much more).
'd'+'rew'='DREW'
Can you help me to learn more?
(Other definitions for drew that I've seen before include "Dragged, finished level" , "Entertainer Barrymore" , "neither won nor lost" , "Ronnie of the Dubliners" , "Sketched or tied in a game" .)
