Ceremonial staff corrals sheep (7)
I believe the answer is:
macrame
'ceremonial' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'staff corrals sheep' is the wordplay.
I cannot really see how this works, but
'sheep' could be 'ram' (male sheep) and 'ram' is present in the answer.
'staff' could be 'mace' (a mace is a ceremonial staff or stick) and 'mace' is located in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for macrame that I've seen before include "Knotted-string work" , "Knotted thread work" , "Decorative knotted work" , "Ornamental work of knotted cord" , "Decorative craft of knotting string" .)
