Queen touring old wing of palace, perhaps (6)

Ross

I believe the answer is:

annexe

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

'wing of palace perhaps' is the definition.
I can't tell whether this defines the answer.

'queen touring old' is the wordplay.
'queen' becomes 'anne' (Queen Anne, 18th-century queen).
'touring' means one lot of letters goes inside another (touring can mean going round).
'old' becomes 'ex' (prefix meaning former or onetime).
'anne' enclosing 'ex' is 'ANNEXE'.

Can you help me to learn more?

(Other definitions for annexe that I've seen before include "Additional room etc for house" , "Building joined to a larger one" , "Building attached to a largerone" , "Wing - extension" , "bit on the side?" .)
