Rambutan or guava (5)
I believe the answer is:
fruit
I believe this clue is a double definition.
'rambutan' is the first definition.
(thesaurus)
'guava' is the second definition.
(thesaurus)
(Other definitions for fruit that I've seen before include "Oranges and lemons" , "Orange, lemon" , "Eg, apple or pear" , "Kiwi, mandarin etc" , "Greengrocer's produce" .)
