Lay and lie
I’m going to lie down for a few minutes.
I’m going to lay this book on the table.
I lay down for 30 minutes, then got up and did my homework.
I laid the book on the table.
Where you at? (ungrammatical slang)
Where are you?
Thanks a lot!
Everyday and every day
He’s an everyday kind of guy.
