Do you itch and itch or scratch an itch 🤔

You scratch an itch..

Scratch is a verb

Itch is a noun

You cannot noun a noun

Hah! I itch an itch

You don't itch an itch, you scratch an itch. Google could've told you the answer immediately without hundreds of people telling you how bad your grammar is.

...and this is the state of our education system.

I've an idea it's a regional thing.

It's not a regional thing, it's scratch an itch - anything else is wrong!

As above, you scratch an itch.
