Eli gives a flowery greeting (3)
I believe the answer is:
lei
'a flowery greeting' is the definition.
(I've seen this in another clue)
'eli gives' is the wordplay.
'gives' is an anagram indicator.
'eli' with letters rearranged gives 'LEI'.
(Other definitions for lei that I've seen before include "Hawaiian flower garland" , "Hawaiian garland - Romanian money" , "Honolulu chain of flowers" , "Floral decoration" , "Garland of flowers in Hawaii" .)
