harmless

An harmless thing or action doesn't hurt anyone.

When we say that something is harmless, we usually mean it's safe and won't cause any problems. For example, if a kid eats some sugar cookies, they might get a stomachache but they're generally considered harmless treats for kids. You can also talk about harmless activities like hiking in the woods or playing with toys - these things are fun without causing harm to anyone. In general, when we call something harmless, we think of it as having no bad effects on people or the environment.
