Like a latte? Kind Knut's round! (5)
I believe the answer is:
milky
'like a latte?' is the definition.
I can't judge whether this definition defines the answer.
'kind knut's round' is the wordplay.
'kind' becomes 'ilk' (ilk can mean a type or kind).
'knut's' becomes 'my' (where the crossword setter is 'Knut').
'round' indicates putting letters inside.
'ilk' put into 'my' is 'MILKY'.
Can you help me to learn more?
(Other definitions for milky that I've seen before include "White, opaque" , "Of a soft white colour" , "Lacteal; cloudy" , "Clouded" , "Lactic" .)
