I search online for the antonym of these words, but I just couldn't find them, so can someone help me?

What are the antonym of these words?


1)magistrate


2)concubine


3)gunnel


4)skiff


5)shuttlecock


6)promontory


7)frond


8)gout





Thanks!!|||Not every noun has an "antonym", where did you get this strange list? Look up the definitions and go from there; I can't imagine that there is a true "antonym" to "shuttlecock" or to "gout". |||They are nouns. That's why.
