leaf: leaf: [OE] Leaf goes back to a prehistoric Germanic *laubaz, which also produced words for ‘foliage’ in other modern Germanic languages (German laub, Dutch loof, Swedish löf, and Danish løv). It is not known for certain where the Germanic word came from, although a connection has been suggested with Russian lupit’ ‘bark’. It may also lie behind the modern English words lobby and lodge.
