Peglike

Peglike is an adjective used to describe objects or features that resemble a peg: typically slender, cylindrical, and of relatively uniform diameter, with a rounded or blunt end. The term is a descriptive descriptor rather than a formal classification and is widely applied across disciplines to convey shape.

In morphology and anatomy, peglike features refer to projections that extend from a surface and may function to anchor, align, or connect with other structures. A common example is the use of peg-like projections in dental or skeletal anatomy, where certain teeth or bone processes are described as peg-shaped or peglike. In botany and paleontology, peglike forms may describe slender, rodlike plant structures or fossilized protrusions.

In materials science, engineering, and related fields, peglike elements are often invoked to convey a cylindrical, dowel-like shape that can serve a joining or alignment role. They are typically characterized by an elongated body with a relatively uniform cross-section and a rounded or blunt tip, though specific applications may introduce variations such as slight tapering or surface texturing.

Differences from related terms: peglike emphasizes the overall peg-like silhouette, whereas terms like pin-like or rod-like highlight other aspects of proportion or extremity. The word is commonly hyphenated as peg-like in formal writing, though peglike is encountered in some styles.
