Being no stay-at-home, he has arranged to stir out (7)
I believe the answer is:
tourist
'being' is the definition.
(tourist is a kind of being)
'no stay-at-home he has arranged to stir out' is the wordplay.
'no stay-at-home he has' becomes 'u' (I can't justify this - if you can you should give a lot more credence to this answer).
'arranged' indicates an anagram.
'out' means one lot of letters goes inside another.
'to'+'stir'='tostir'
'tostir' with letters rearranged gives 'torist'.
'u' placed inside 'torist' is 'TOURIST'.
Can you help me to learn more?
(Other definitions for tourist that I've seen before include "Holiday traveller" , "Cheap travel class" , "someone on holiday" , "Person travelling for pleasure" , "Someone who travels for pleasure" .)
