Part of speech: verb

Definitions

Etymology: Oversewing is a plain compound: the prefix "over-" attached to "sew," so the sense is roughly "sewing over" an edge. The stitch itself works by looping thread over the raw edge of fabric, binding the fibres together so they cannot fray. Because the stitch wraps the edge rather than running across the cloth, it forms a firm border that resists unravelling. The verb "oversew" follows the same pattern as other "over-" compounds in English, where the prefix signals action passing across or upon something, as in "overlay" or "overlook." Here the object being covered is the raw margin of a piece of cloth.
