stamdeel

Stamdeel is a Dutch noun meaning the main part or central section of an object or organism. It derives from stam ("stem, trunk") combined with deel ("part"). The term appears primarily in technical or descriptive Dutch and is not a common everyday word. It is used to distinguish a central, structural portion from peripheral parts such as leaves, roots, or attachments.

In botany and horticulture, stamdeel can denote the main axis of a plant stem—the portion that bears buds, nodes, and leaves—and is sometimes used in growth descriptions, pruning plans, or grafting contexts. In anatomy or physiology, stamdeel may refer to the central body of a structure when contrasting it with extremities or appendages. In mechanical engineering or manufacturing, it can label the main shaft or trunk-like portion of a component, separating it from end fittings, gears, or fasteners.

In linguistics and language studies, stamdeel is occasionally used to describe the stem or core part of a word, i.e., the form remaining after affixes have been removed. However, this usage varies by author, and native Dutch speakers more often employ terms like stam or wortstam when discussing morphology. As with many compound terms, context and field determine whether stamdeel is understood.
