As embracing Goneril finally, her father very attentive (3,4)
I believe the answer is:
all ears
'very attentive' is the definition.
(I've seen this before)
'as embracing goneril finally her' is the wordplay.
'embracing' indicates putting letters inside.
'finally' indicates one should take the final letters.
'her' becomes 'lear' (I am not sure about this - if you are sure you should believe this answer much more).
The final letter of 'goneril' is 'l'.
'l'+'lear'='llear'
'as' enclosing 'llear' is 'ALL EARS'.
'father' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for all ears that I've seen before include "Being very attentive" , "Very alert" , ".Listening very intently" , "Listening attentively" , "Prepared to listen" .)
