Admirer of oddly stupid, yet rugged, prominence (6)
I believe the answer is:
suitor
'admirer' is the definition.
(suitor is a kind of admirer)
'oddly stupid yet rugged prominence' is the wordplay.
'oddly' indicates alternate letters (letters in the odd-numbered positions are used).
'yet rugged prominence' becomes 'tor' (I can't explain this - if you can you should believe this answer much more).
The alternate letters of 'stupid' are 'sui'.
'sui'+'tor'='SUITOR'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for suitor that I've seen before include ". . . he woos his girl" , "Man pursuing a woman for marriage" , "A man wooing" , "He pays court to a woman" , "Man who is courting a woman" .)
