Generous with son in domestic situation (8)
I believe the answer is:
handsome
'generous' is the definition.
(similar in meaning)
'with son in domestic situation' is the wordplay.
'with' becomes 'and'.
'son' becomes 's' (genealogical abbreviation for son).
'in' indicates putting letters inside.
'domestic situation' becomes 'home' (I can't explain this - if you can you should give a lot more credence to this answer).
'and'+'s'='ands'
'ands' going inside 'home' is 'HANDSOME'.
Can you help me to learn more?
(Other definitions for handsome that I've seen before include "Pleasing in appearance" , "beautiful" , "Fit" , "Easy on the eye" , "Attractive in a strong, imposing way" .)
