Hot drink medical attendant holds (5)
I believe the answer is:
latte
'hot drink' is the definition.
(type of coffee drink)
'medical attendant holds' is the wordplay.
'holds' indicates a hidden word.
'LATTE' is hidden in the letters of 'medical attendant'.
(Other definitions for latte that I've seen before include "Coffee beverage" , "Kind of espresso coffee" , "Type of coffee" , "See 21" , "Coffee with a topping of frothed steamed milk" .)
