unimportant

An unimportant thing or situation isn't crucial or essential.

When we say that something is unimportant, we usually mean it's not vital to our daily lives or decisions. For example, if someone asks for your opinion on a minor issue, you might tell them it's unimportant and they shouldn't worry about it. You could also call a small event unimportant because it doesn't have much impact on the bigger picture. In some cases, when something is being discussed but nobody really cares about it, people might say it's "unimportant" to change the subject or move on from that topic.
