Beware the legendary ones bearing gifts (6)
I believe the answer is:
greeks
'beware the legendary ones bearing gifts' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for greeks that I've seen before include "Athenians, maybe" , "Virgil: 'I fear the ...... bearing gifts'" , "Natives of Athens" , "Demos" , "Beware the legendary ones bearing gifts" .)
