Did you know?

Since the prefix hyper- means "above, beyond", hyperkinetic describes motion beyond the usual. The word is usually applied to children, and often describes the condition of almost uncontrollable activity or muscular movements called attention-deficit/hyperactivity disorder *(ADHD). Kids with ADHD are usually not just hyperkinetic but also inattentive, forgetful, and flighty. Though they're often treated with drugs, many experts believe there are better ways of dealing with the problem. Lots of people now shorten both *hyperactive and hyperkinetic to simply hyper ("He's been hyper all morning"), but usually don't mean it too seriously.
