Spanish friend becomes an egomaniac once acne clears up (5)
I believe the answer is:
amigo
'spanish friend' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for amigo that I've seen before include "Friend from Spain?" , "buddy abroad?" , "friend from Barcelona" , "A Spanish pal" , "friend abroad" .)
