Trying again to hug son getting ready to perform (10)
I believe the answer is:
rehearsing
'ready to perform' is the definition.
I can't judge whether this defines the answer.
'trying again to hug son' is the wordplay.
'trying again' becomes 'rehearing' ('hearing' can be a synonym for 'trying' so perhaps 'rehearing' is OK for 'trying again').
'to hug' indicates putting letters inside (inserted letters are hugged).
'son' becomes 's' (genealogical abbreviation for son).
'rehearing' enclosing 's' is 'REHEARSING'.
'getting' is the link.
Can you help me to learn more?
(Other definitions for rehearsing that I've seen before include "Practising (a play)" , "getting ready for a show?" , "Preparing for a play" , "Getting ready for the big night" , "Trying out" .)
