Not important or influential
Not important enough to matter or to change something.
用法パターン：
[something] is insignificant
よくある間違い：
Learners sometimes use "insignificant" when they mean "small" in a physical sense, even if the thing is still important. Use "insignificant" when the size, effect, or importance is too low to really matter, not just when something is physically small.
類義語
unimportant (More direct and common; slightly less formal than "insignificant".)
|
trivial (Suggests something is not only unimportant but almost silly or not worth thinking about.)
|
negligible (Often used in more formal or technical contexts; stresses that something can be safely ignored.)
対義語

Very small in size or amount
Very small in number, size, or level, so that it is almost not worth thinking about.
用法パターン：
an insignificant amount of [something]
よくある間違い：
Learners sometimes use "insignificant" when they simply mean "small" without the idea that it can be ignored. If the small amount still matters (for example, a small but dangerous dose of a drug), "insignificant" is not appropriate.
類義語
minimal (Focuses on the amount being the smallest possible; often neutral or technical.)
|
tiny (More informal and visual; stresses small physical size rather than importance.)
対義語
substantial (Stresses a large or considerable amount, often with the idea that it matters.)
|
considerable (Suggests a fairly large amount that draws attention.)

Feeling small or unimportant
Feeling or being seen as not important, especially when you compare yourself with others or with something very big.
用法パターン：
[someone] feels insignificant
よくある間違い：
Learners sometimes confuse "insignificant" with "insecure." "Insignificant" is about being or feeling unimportant; "insecure" is about not feeling safe or confident. A person can feel insecure even if they are important.
類義語
worthless (Much stronger and more emotional; suggests having no value at all, often used about feelings of depression or low self-esteem.)
|
unnoticed (Focuses on not being seen rather than on lack of importance, but often overlaps in feeling.)
対義語
important (Describes someone who has status, power, or a strong effect on others.)
|
valued (Focuses on being appreciated and seen as important by others.)

Not statistically significant
In statistics, too small or weak to show that something is real and not just random chance.
用法パターン：
a statistically insignificant [result]
よくある間違い：
Learners may think "statistically insignificant" means "not interesting" or "not useful." In statistics it has a specific technical meaning: the data do not clearly show a real effect beyond random chance, even if the topic is important.
類義語
non-significant (Technical term used in statistical writing; interchangeable in this context.)
対義語
statistically significant (Means the result is strong enough that it is unlikely to be due to chance.)
