Beau finally pierces nipple area, getting golden ring (7)
I believe the answer is:
aureola
'golden ring' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'beau finally pierces nipple area getting' is the wordplay.
'finally' suggests the final letters.
'pierces' means one lot of letters goes inside another (some letters pierce a hole in others).
'nipple' becomes 'ol' (I can't justify this - if you can you should give a lot more credence to this answer).
'getting' means one lot of letters goes inside another.
The final letter of 'beau' is 'u'.
'ol' placed within 'area' is 'areola'.
'u' inserted inside 'areola' is 'AUREOLA'.
Can you help me to learn more?
(Other definitions for aureola that I've seen before include "Halo-like form" , "Corona round sun/moon" , "Halo; corona" , "headlight" .)
