What term is used to describe something that can be ignored or considered unimportant?

The term "negligible" refers to something so small or unimportant that it can be disregarded or considered insignificant in a particular context. When something is deemed negligible, it implies that it has no substantial impact or effect on the situation at hand. This makes it an appropriate choice for describing matters that do not require attention or concern.

While "minor," "insignificant," and "trivial" also suggest a lack of importance, "negligible" specifically emphasizes that the item or concern can be completely overlooked without consequence, often used in mathematical or scientific contexts to signify values or errors that are so small they do not affect the outcome. This nuance makes "negligible" the most fitting term for the question asked.
