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 l?f, and Danish l?v). 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.

Old English leaf "leaf of a plant; page of a book," from Proto-Germanic *laubaz (cognates: Old Saxon lof, Old Norse lauf, Old Frisian laf, Dutch loof, Old High German loub, German Laub "foliage, leaves," Gothic lauf), perhaps from PIE *leup- "to peel off, break off" (cognates: Lithuanian luobas, Old Church Slavonic lubu "bark, rind").
