For the idiots:
Unfortunately most online dictionary sources (the good ones, including the OED, Theosaurus.com, Merrium-Webster are paywalled and require membership. Or you could, you know, just pick up a damn dictionary.
Oxford Leaner's Dictionary (if using their online search) only lists Dominatrix which, I'll explain, as you won't know this either, is from the Latin word dominator, which is the feminine form of the word dominat-, meaning "ruled". Dominat- comes from the verb dominari,

Who'd of thought huh...and is used in
sexual activity. But hey, it's not like I'm actually educated on this subject (or English as a subject itself for that matter), so:
Like seriously, how many examples do you actually need? See the common theme? Sexual practices/activities? Cambridge, Oxford, Collins yeah, they all don't have a clue and are all wrong. Maybe in your fit trying to be right, you should perhaps write to all these organisations and tell them how they are wrong, So please feel free to continue arguing and swinging your dicks around amongst yourselves in a vain attempt to try and one-up me, but I won't be seeing anymore of your nonsense either way.
