Not all antelope run easily (4)
I believe the answer is:
This clue could be a double definition.
'not all antelope' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'run easily' is the second definition.
Can you help me to learn more?
(Other definitions for lope that I've seen before include "Go with bounding strides" , "run gently" , "Run with long steps carrying pole" , "Run with aid of pole" , "Run slowly with pole" .)
