Wings quit fancy show with covers from Vanity and Fish (7)
I believe the answer is:
anchovy
'fish' is the definition.
(anchovy is a kind of fish)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for anchovy that I've seen before include "Small fish of herring family, nice on toast" , "Small fish, may be served with toast." , "Tiny fish, usually canned" , "Strong-flavoured fish" , "Small fish used in making sauce, paste etc" .)
