Etymology: "Knob" came into English in the Middle English period, probably from a Low German or Dutch source like "knobbe," a word for a lump or protuberance. From it grew a family of lump-related forms, and "knobble" and "knubble" are variants in that family. The "-le" ending is a frequentative suffix, which makes a repeated or ongoing action out of a root, so a verb like "knubble" suggests something that keeps bunching up into bumps. The "-ing" ending makes "knubbling" a participle, the form used for an ongoing action. Its use in English is largely dialectal or informal, and the root sound is close to "knub," an older form used for a small rounded lump. Its exact early history is uncertain, so the pathway is best read as a likely rather than fully documented one.
