Something that is unimportant lacks significance or value. Unimportant details in a movie, for instance, add little to the story. Something that is negligible is so small, trifling, or unimportant that it may safely be neglected or disregarded. Negligible carries no positive or negative force on its own; when it describes something undesirable, like damage, negligible can come as a relief: The couple was relieved to learn that water damage to their home was negligible. But when it is describing something more desirable, like financial growth, negligible can connote disappointment: Much to the chagrin of investors, the company’s growth in the last year was negligible.
