Towers over (6)
I believe the answer is:
dwarfs
'towers over' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dwarfs that I've seen before include "Snow-white had seven of these companions" , "Small people like Snow white's" , "Mythical short beings" , "Short mythical creatures" , "See 6" .)
