minor

MY-ner

meaning in plain English

Someone who is still a child or young person and not yet considered a full adult by the law.

Picture a minor key on a piano—small, not adult, just a kid's tune.

for example

You can't buy a gun if you're a minor under eighteen years old.

Imagine you're at a store and see a sign that says 'No alcohol for minors.' Why does it say that? Because the law says kids aren't old enough to make those choices yet.
