hyper

An adjective "hyper" describes someone or something that's extremely good at what they do, or has an unusually high level of enthusiasm.

When we call someone hyper, it means they have lots of energy and are very excited about everything. Imagine a kid running around nonstop in a playground – that's the kind of hyper energy we're talking about. You might say "He's so hyper today, always jumping up and down!" This can be a little bit annoying to adults, but it's also kind of cute. Some people even use the word "hyper" as an insult, meaning someone is being too energetic or annoyingly enthusiastic. However, in general, when we describe something as hyper, we mean that it has an above-average level of excitement or energy.

The word "hyper" can also be used to describe objects with high performance capabilities – like a super-fast computer or an incredibly powerful engine. For example: "This new gaming laptop is really hyper, I can play games at insane resolutions!" In this case, we're talking about the machine's exceptional abilities and performance, not its emotional state.

Note that there's also a medical term "hyper-" used in words like hypertension (high blood pressure) or hyperventilation, but these are more technical uses of the word. The adjective form is what most people use to describe energetic people or things.
