Usage
What’s the difference between itch and scratch? An itch is a feeling of irritation on the skin, often one that makes you want to scratch it (scrape it or rub it). The word itch can also be used as a verb meaning to have this sensation (as in My leg itches) or to cause to itch (as in The tag on my shirt keeps itching me). Itch also has some more figurative meanings as both a noun and a verb. The reason you looked this up, though, is because itch is sometimes informally used to mean the same thing as scratch, as in Try not to itch your mosquito bites—it will only make them itchier! Language purists are often itching to clarify that you scratch an itch, but this verb use of itch is quite common. As a noun, the word scratch means something different—a cut or scrape, typically a minor one caused by something having scratched the skin, as in I got a few scratches from the thornbush. Here’s an example of itch and scratch used correctly in the same sentence. Example: I know your rash itches, but don’t scratch your itch so hard—you’ll leave a scratch on your arm!Want to learn more?

Etymology
Origin of itch
First recorded before 900; Middle English verb (y)icchen, Old English gicc(e)an; akin to German jucken, Dutch jeuken; noun derivative of the verb
Explanation
An itch is an unpleasant tingly sensation that makes you want to scratch. If you're allergic to poison ivy and you go hiking through a field of it, you'll have a terrible itch all over your legs. Sometimes people confuse itch and scratch. An itch is the sensation that causes you to scratch, and when itch is a verb, it either means "to feel or sense an itch," or "to have a strong, restless urge," as when you itch to try out your uncle's motorcycle. Somehow, the word itch arose from its Old English root gicce, or gycce, "an itch."
