Young boy embracing a learner in artistic gathering (5)
I believe the answer is:
salon
'artistic gathering' is the definition.
(salon can mean a gathering of artists)
'young boy embracing a learner' is the wordplay.
'young boy' becomes 'son' (male child).
'embracing' indicates putting letters inside.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'a'+'l'='al'
'son' enclosing 'al' is 'SALON'.
'in' is the link.
(Other definitions for salon that I've seen before include "Room where beautician works" , "Call loudly" , "Drawing room" , "Elegant reception room" , "Hairdresser's establishment" .)
