Effeminate applications in college grounds (8)

Ross

I believe the answer is:

campuses

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

'college grounds' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how they can define each other.

'effeminate applications' is the wordplay.
'effeminate' becomes 'camp' (I've seen this before).
'applications' becomes 'uses' (I've seen this before).
'camp'+'uses'='CAMPUSES'

'in' acts as a link.

Can you help me to learn more?

(Another definition for campuses that I've seen is " Grounds and buildings of colleges".)

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