Someone who gives others a hand (6)
I believe the answer is:
dealer
'someone who gives others a hand' is the definition.
(a dealer gives people their hands in a card game)
'hand' is the wordplay.
I cannot really understand how this works, but
'hand' could be 'deal' ('deal' can be a synonym of 'hand') and 'deal' is found within the answer.
The remaining letters 'er' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dealer that I've seen before include "Card distributor" , "One who trades, perhaps on stock exchange" , "Trader; card player" , "Trader; issuer of hands" , "Trader - distributor of cards" .)
