Daughter's keen on Beckham (5)
I believe the answer is:
david
'beckham' is the definition.
I can't judge whether this definition defines the answer.
'daughter's keen on' is the wordplay.
'daughter' becomes 'd'.
'keen' becomes 'avid' (I've seen this before).
'on' says to put letters next to each other.
'd'+'avid'='DAVID'
Can you help me to learn more?
(Other definitions for david that I've seen before include "singer/harpist?" , "The Psalmist" , "Israeli king" , "Man's name" , "King of Judah and Israel, Saul's successor" .)
