“Aptronym”

When someone’s name is fitting for their occupation.

Tiger Woods (like the gold club)

Usain Bolt (who bolts quickly)

Etc.

Also whatever this is https://en.wikipedia.org/wiki/Buffalo_buffalo_Buffalo_buffalo_buffalo_buffalo_Buffalo_buffalo

I’m a big fan of contronyms, words with two opposite meanings. I first learned looking for a word to describe the change in “literally” from meaning, well, the literal meaning of something to also the figurative meaning.

Another good one is dust. You can dust your house to remove dust, but you can also dust a cake with powdered sugar.

Malaphors are my faves. Like saying "we’ll burn that bridge when we get to it*

I enjoy “portmanteau”: the combination of two words to get a new meaning.“Brunch”

Malapropisms are great, too. “He hits from both sides of the plate. He’s amphibious”
