Bit of mango fruit topped for later (6)
I believe the answer is:
manana
'later' is the definition.
(thesaurus)
'bit of mango fruit topped' is the wordplay.
'bit of' indicates taking the first letters.
'fruit' becomes 'banana' (type of fruit).
'topped' means to remove the first letter (to top something is to remove its top).
The initial letter of 'mango' is 'm'.
'banana' with its first letter taken away is 'anana'.
'm'+'anana'='MANANA'
'for' acts as a link.
(Other definitions for manana that I've seen before include "Some indefinite time in the future (Spanish)" , "later in Spain" , "Tomorrow in Barcelona" , "It's tomorrow, senor" , "Sharply-defined" .)
