Etymology: The noun derived from the verb "knob" has roots in Middle English, where "knobbe" meant a small lump or protuberance, likely related to the Old Norse "knappr," meaning a button or a knob. The word originally described a rounded lump, often on wood or other surfaces. Over time, the verb form emerged, meaning to strike or hit with a knob-like object or to form into a knob. The suffix "-ing" converts the verb into a noun indicating the action or process, so "knobbing" refers to the act of making knobs, hitting with a knob, or forming lumps. This verbal noun construction became more common in English from the late Middle Ages onward, as the language developed more flexible uses of suffixes to create action nouns. Though not commonly used in contemporary speech, the term would historically appear in contexts describing crafts such as woodworking or in colloquial expressions for hitting or bumping with a rounded object. Its formation follows a typical pattern of English word-building, where a concrete noun evolves into a verb and then into a verbal noun to capture the action related to the original object.
