Could you break this down? The wordplay is eluding me.

Apparently, dunk the non-binary to be pseudointellectual and nonsensical.

(8 letters)

Apparently - sounds like

dunk - ret, as in submerge and soak in water

the non-binary - toric - a non-binary individual

to be pseudointellectual and nonsensical - Rhetoric (self-explanatory)

Please let me know if any issues.

Just to add if the answer is not self-explanatory:

One is viewed to be engaging in rhetoric if they are talking in a way to appear intelligent, but their jibber jabber doesn't make sense. A good example is a current world leader who is in the news a lot ATM!

Atibhoti..

Aperitif…?

Might the cockscomb be a high court requirement? (8)
