What does the term negligible mean?

The term "negligible" refers to something that is so small or unimportant that it can be ignored or disregarded. In this context, the meaning aligns closely with the description of being "unimportant." When something is considered negligible, it does not have a significant impact or influence on a situation or outcome, allowing it to be overlooked without consequence.

In contrast, the other options present opposing concepts. "Necessary" implies that something is essential and cannot be overlooked. "Significant" suggests that a particular item or factor is important or has a considerable effect. "Notable" indicates that something deserves attention due to its importance or remarkable qualities. Therefore, "unimportant" accurately captures the essence of the word "negligible."
