Simply to meet the case (2,3)

Ross

I believe the answer is:

ad hoc

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

'case' is the definition.
(I have seen 'particular case' mean 'ad hoc' so perhaps 'case' could also mean 'ad hoc')

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for ad hoc that I've seen before include "For a specific purpose - latin phrase" , "Done for a particular purpose only" , "not in general practice" , "particular case" , "Devised for one particular occasion" .)

I've seen this clue in the Evening Standard.
