In southern Europe, one has to live on air, maybe! (6)
I believe the answer is:
iberia
'in southern europe' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'one has to live on air maybe' is the wordplay.
'one' becomes 'I' (Roman numeral).
'has' says to put letters next to each other.
'to live' becomes 'be' ('be' can be a synonym of 'live').
'on' is a charade indicator (letters next to each other).
'maybe' indicates an anagram.
'air' anagrammed gives 'ria'.
'i'+'be'+'ria'='IBERIA'
Can you help me to learn more?
(Other definitions for iberia that I've seen before include "old part of Europe" , "SW European peninsula" , "Peninsula housing Spain and Portugal" , "Overpower, overwhelm" , "Great European peninsula containing Spain and Portugal" .)
