Fruit from citron removed from morning coat (5)
I believe the answer is:
mango
'fruit' is the definition.
(mango is a kind of fruit)
'from citron removed from morning coat' is the wordplay.
'from' indicates an anagram (from the letters).
'removed from' is a deletion indicator.
'morning'+'coat'='morningcoat'
'morningcoat' with 'citron' removed is 'mngoa'.
'mngoa' is an anagram of 'MANGO'.
(Other definitions for mango that I've seen before include "Type of fruit" , "Yellow-fleshed fruit" , "Once exotic fruit" , "Asian fruit" , "fruit tree" .)
