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 don't understand the rest of the clue.
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" .)
