Attracted many with a share of the reward (4)
I believe the answer is:
drew
'attracted' is the definition.
(I've seen this in another clue)
'many with a share of the reward' is the wordplay.
'many' becomes 'D' (Roman numeral for 500).
'with' means one lot of letters go next to another.
'a share of the reward' becomes 'rew' (I can't explain this - if you can you should give a lot more credence to this answer).
'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" .)
