Mary and child featured in stonework (7)
I believe the answer is:
masonry
'stonework' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for masonry that I've seen before include "Stonework" , "Building work in stone" , "brickwork" , "Skill in construction" .)
