| 释义 | unit (once / 160 pages) 1n 2n A unit is a single, whole part of something, like a building block. In math class, you might do a unit on algebra before you do another unit on geometry. Also, there are units of measurement, such as inches and miles. The word unit started out in math but has branched out to refer to any singular thing that is part of something larger. Each apartment in a building is a unit. A unit can also be a small group that fits into a larger social organization, like a military unit or a family unit. In all cases, a unit is a small, whole part of something bigger.
