Clothed and ready for college (6)
I believe the answer is:
girton
'college' is the definition.
(I've seen this before)
'clothed and ready' is the subsidiary indication.
'clothed' becomes 'girt' (I can't explain this - if you can you should believe this answer much more).
'and' is a charade indicator (letters next to each other).
'ready' becomes 'on' (if a device is on it is ready for use).
'girt'+'on'='girton'
'for' is the link.
Can you help me to learn more?
(Another definition for girton that I've seen is " First women's college, Cambridge".)
