nonsignificant

If something is nonsignificant, it is too small or unimportant to matter much. It may be there, but it does not change the bigger picture in any real way. Think of a tiny speck of dust on a large painting: you can see it, but it does not change what the painting is.

The word is also common in science and statistics. There, it often means a result was not strong enough to count as meaningful. A nonsignificant difference between two groups, for example, suggests the gap may be due to chance rather than a real pattern. In everyday writing, it can also describe a small detail, such as a nonsignificant delay that does not cause real trouble.

"Nonsignificant" describes something that is not important enough to have a real effect. It can refer to a detail, change, or difference that is too small to matter in practice. In that broad sense, it is close to "insignificant," though "nonsignificant" often sounds more formal and is less common in ordinary conversation.

The word is especially common in scientific and statistical contexts. There, it usually means that a result is not statistically meaningful. For example, a researcher might say that the difference between two test groups was nonsignificant. In that case, the observed gap was not strong enough to show a clear real effect, and it may simply be due to chance.

Outside technical writing, the word can still describe something minor or unimportant, but this use is less common than with "insignificant." You might use it for a small delay, a slight change in cost, or a difference so small that it does not affect a decision. For instance, if the price gap between two products is nonsignificant, you may choose based on quality instead.

So when something is nonsignificant, it is present but not important enough to change the outcome, the meaning, or the decision. In research, that often means "not statistically significant." In general writing, it usually means "too minor to matter."
