The word "etch" means to carve or cut into a hard surface, such as metal or glass, to create a design or pattern. This can be done using tools like acid or a sharp instrument, like a needle. For example, if you want to decorate a drinking glass with your initials, you can etch them into the glass using a special tool. This will create a permanent design on the glass that won't come off even after washing. The word "etch" can also be used more broadly to describe any type of permanent marking or impression. For instance, if someone's words or actions leave a lasting impression on you, you could say that they "etched" themselves into your memory. Overall, the word "etch" is most commonly used when talking about creating designs or markings on hard surfaces, whether that be for artistic, decorative, or practical purposes.
