Split dance for tea (3)

I believe the answer is:

cha

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

'for tea' is the definition.
(cha is a type of tea)

I don't understand how the rest of the clue works.

(Other definitions for cha that I've seen before include "not allowed in ski lodge" , "Tea (colloquial)" , "Tea (colloq.)" , "drink" , "Tea (informal)" .)

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