Extra-short

Extra-short refers to something that is very, very small. It's like when you eat a tiny piece of candy and it is so small that you can barely see it. Extra-short things can be really helpful for things like making tiny parts for toys or electronics. It can also be used to describe how short a length of time is. For example, if you only have a very short amount of time to do something, you might say it's extra-short. So basically, extra-short means very small or not a lot of time.
