Give free medical attention? (5)

I believe the answer is:

treat

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

'give' is the definition.
(I know that treat is a type of give)

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

Can you help me to learn more?

(Other definitions for treat that I've seen before include "Deal with - source of great pleasure" , "Doctor, manage" , "Tend" , "Special delight; handle" , "Enjoyable party" .)

I've seen this clue in The Globe and Mail.
