Try diamonds with gown? Not right for beautiful woman (7)
I believe the answer is:
goddess
'beautiful woman' is the definition.
'try diamonds with gown? not right' is the wordplay.
'try diamonds with' becomes 'god' (I am not sure about this - if you are sure you should believe this answer much more).
'gown?' becomes 'dress' (gown is a kind of dress).
'not' indicates named letters should be taken away.
'right' becomes 'r' (common abbreviation).
'dress' with 'r' taken away is 'dess'.
'god'+'dess'='GODDESS'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for goddess that I've seen before include "Eg, Aphrodite" , "divinity" , "Divine female" , "Such as Venus" , "Say Athena" .)
