One business area for Mediterranean resort (5)
I believe the answer is:
ibiza
'mediterranean resort' is the definition.
'ibiza' can be an answer for 'resort' (I've seen this before). I'm unsure of the 'mediterranean' bit.
'one business area' is the wordplay.
'one' becomes 'i' (Roman numeral).
'business' becomes 'biz' (informal term for business).
'area' becomes 'a' (maths abbreviation).
'i'+'biz'+'a'='IBIZA'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for ibiza that I've seen before include "Westernmost of Balearic islands, and its capital" , "holiday venue" , "Island in the Balearics" , "Holiday island" , "Westermost of Balearic Islands, popular for holidays" .)
