Century Dictionary and Cyclopedia

1. n. A heavy sword having a single edge, and thickest at the back of the blade, tapering gradually toward the edge. It is usually slightly curved; but some cavalry sabers are perfectly straight. The saber may be considered as a modification of the Oriental simitar increased in weight and diminished in curvature, and differs from the typical sword, which is double-edged, with its greatest thickness in the middle of the blade.
2. n. A soldier armed with a saber.
3. To furnish with a saber.
4. To strike or cut with a saber.
