Try some of latte MP tasted (7)
I believe the answer is:
attempt
'try' is the definition.
(I know that try can be written as attempt)
'some of latte mp tasted' is the wordplay.
'some of' indicates a hidden word.
'ATTEMPT' is hidden within 'latte mp tasted'.
(Other definitions for attempt that I've seen before include "bid to kill someone" , "Try, hazard" , "Try to climb (a peak)" , "Try, endeavour" , "bash" .)
