Elevator name (4)
I believe the answer is:
otis
'elevator name' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for otis that I've seen before include "US inventor" , "Place of worship; side part of head" , "---- Redding, 1941-67, soul singer" , "- - Redding (soul music star)" , "-- Redding, US singer" .)
