Alfresco exit (7)
I believe the answer is:
outdoor
'alfresco' is the definition.
(similar in meaning)
'exit?' is the wordplay.
I cannot quite see how this works, but
'exit?' could be 'door' (I've seen this in another clue) and 'door' is found in the answer.
The remaining letters 'out' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for outdoor that I've seen before include "healthy pursuits" , "Used in the open air" , "not under cover" , "Located in the open air" , "This sport is not under a roof" .)
