More often than not, Rodriguez has virile exterior (6)
I believe the answer is:
mainly
'more often than not' is the definition.
Both the answer and definition are adverbs. Maybe there's a link between them I don't understand?
'rodriguez has virile exterior' is the wordplay.
I cannot really see how this works, but
'rodriguez' could be 'i' (where the crossword setter is 'Rodriguez') and 'i' is found within the answer.
'virile' could be 'manly' (synonyms) and 'manly' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for mainly that I've seen before include "Chiefly, principally" , "For the most part" , "Chiefly, largely" , "Generally or largely" .)
