Do wrong in giving players a hand (7)
I believe the answer is:
misdeal
'do wrong' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'giving players a hand' is the wordplay.
'giving players' becomes 'mis' (I can't justify this - if you can you should believe this answer much more).
'a hand' becomes 'deal' (synonyms).
'mis'+'deal'='MISDEAL'
'in' is the link.
Can you help me to learn more?
(Other definitions for misdeal that I've seen before include "Wrongly issue" , "Faulty distribution" , "Faulty issue of cards" , "Give out cards incorrectly" , "Right hand that isn't" .)
