*lubīherb, plant*lew-to cut, remove, prune, separate
nounneuterja-stemwort, herbpoisonlove potionFrom Proto-Indo-European *lubʰ-yo-, from *lewbʰ- (‘herb’), and cognate with Proto-Celtic *lubī (‘herb, plant’). The root is likely equivalent to *lewbʰ- in the "peel, break, damage" sense (likely whence Proto-Germanic *laubą (‘leaf’)), which itself has been further derived from a Proto-Indo-European *lew- (‘to cut, remove, prune, separate’); the semantic development would be something like "peeled-off plant matter" > "herb" > "potion (made from herbs)".The sense of love potion is influenced by similar forms from the unrelated *lubō (‘love’).
