Expel entry in the open air (7)

Ross

I believe the answer is:

outdoor

I'm a little stuck... Click here to teach me more about this clue!

'in the open air' is the definition.
(I've seen this before)

'expel entry' is the wordplay.
'expel' becomes 'out' (I can't explain this - if you can you should believe this answer much more).
'entry' becomes 'door' (synonyms).
'out'+'door'='OUTDOOR'

Can you help me to learn more?

(Other definitions for outdoor that I've seen before include "Alfresco - sort of pursuits" , "Done in the open" , "exposed to the elements" , "External" , "Al fresco" .)

I've seen this clue in the Sydney Morning Herald.
