I believe the answer is:

nurse

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

'minister to' is the definition.
(I've seen this in another clue)

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

Can you help me to learn more?

(Other definitions for nurse that I've seen before include "Entangle" , "Slow-moving shark" , "Minister to" , "One caring for patient" , "Cherish" .)

I've seen this clue in The Times.
