Cage makers? (4)
I believe the answer is:
Here is my best explanation:
This clue might be a double definition.
'cage' is the first definition.
(I've seen this before)
'makers?' is the second definition.
Although both the answer and definition are plural nouns, I can't understand how one could define the other.
(Other definitions for ribs that I've seen before include "Spurs?", "Chest bones, may be floating", "Bones in chest, may be floating", "Teases (informal)", "cage", "Arched bones extending from the spine", "Pairs of curved bones", "Curved bones around the chest", "Is making fun of" and "Arched bones in the upper body".)
