Devoted fan of Aida icon possibly? (10)

I believe the answer is:

aficionado

I'm a little stuck... Click here to teach me more about this clue!

'devoted fan' is the definition.
'aficionado' can be an answer for 'fan' (I've seen this before). I'm unsure of the 'devoted' bit.

'of aida icon possibly?' is the wordplay.
'possibly?' is an anagram indicator (I've seen 'possibly' mean this).
'of'+'aida'+'icon'='ofaidaicon'
'ofaidaicon' with letters rearranged gives 'AFICIONADO'.

Can you help me to learn more?

(Other definitions for aficionado that I've seen before include "ardent follower" , "Fan; enthusiast" , "Informed enthusiast" , "Fan (Sp.)" , "freak" .)

I've seen this clue in The Times.
