Where, in Iberia, music can take root? (6)
I believe the answer is:
Here is my best explanation:
'where in iberia music' is the definition.
The definition suggests a singular noun which matches the answer.
'can take root?' is the wordplay.
I cannot quite understand how this works, but
'take' could be 'r' (recipe is latin for take - r is abbreviation) and 'r' is found within the answer.
'can' could be 'pot' ('pot' can be a synonym of 'can') and 'pot' is present in the remaining letters.
The remaining letters 'oo' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
(Other definitions for oporto that I've seen before include "European city", "Portugal's second city", "Second largest city in Portugal", "City of Portugal", "Portuguese wine city", "Iberian city", "foreign place", "City near the mouth of the River Douro", "Portuguese wine trade centre" and "Iberian location".)
