A giant bound? (5)
I believe the answer is:
atlas
This might be a double definition.
'a giant' is the first definition.
(I've seen this before)
'bound?' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
Can you help me to learn more?
(Other definitions for atlas that I've seen before include "Size of paper once" , "A geog. book; N. African range" , "used for maps" , "Plans" , "African mountain range" .)
