You missed one particular class of typo.

- Three physicist were there

- Six dentist agree

- All the specialist are here

Specifically, plural words ending in -ist, if you say them quickly, it’s easy to drop the final -s.

Why in the world would you leave it off when typing? Because you’re typing what you hear as you “say” it in your head.

I find it fascinating and super annoying. It’s jarring every time I read it.
