clog (English)

Where does "clog" come from?

The origin of the English verb 'clog' remains unknown, though it may derive from the Middle English noun 'clog', meaning a weight attached to the leg of an animal to impede movement[1]. This term is potentially of North Germanic origin, tracing back to the Proto-Germanic form '*klumpô', which means 'lump, mass, or clasp'[1]. Related regional comparisons include Old Norse 'klugu' and Dutch 'klomp'[1].
