Stiffeners to spare? (4)
I believe the answer is:
ribs
'stiffeners' is the definition.
Although both the answer and definition are plural nouns, I don't understand how they can define each other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for ribs that I've seen before include "Teases (informal)" , "Makes fun of - bones" , "Chest bones, tasty when spare" , "Arched bones extending from the spine" , "Curved bones around the chest" .)
