A more thorough explanation:

Levis

Levis means something that is light or unimportant. It comes from the Latin language.

• Her levis backpack was easy to carry around all day.
• The teacher didn't give much importance to the levis mistake in the student's essay.

The first example shows that the backpack was light and easy to carry. The second example shows that the mistake in the essay was not a big deal and was considered unimportant.
