Bony thing, angle on figure by the sound of it? (6)
I believe the answer is:
coccyx
'bony thing' is the definition.
(coccyx is a type of bone)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for coccyx that I've seen before include "Bone of lower spine" , "Tail bone" , "fused vertebrae" , "bit of backbone" , "Small triangular bone at base of spine" .)
