leaf (English)

Where does "leaf" come from?

The English noun 'leaf' traces its lineage through Middle English 'leef' and Old English 'lēaf'[1][3]. This descends from Proto-West Germanic '*laub' and Proto-Germanic '*laubą'[1][2][3], which itself likely derives from the Proto-Indo-European root '*lewbʰ-' meaning to cut off or peel off[1]. Across its ancient history, related forms evolved to describe plant foliage, tree bark, and peeled layers across many Indo-European languages.

Open questions

The derivation of Proto-Germanic '*laubą' has differing explanations, as it is variously connected to Proto-Indo-European '*lewbʰ-' or pre-Germanic '*lowpóm' with an unknown connection between the two roots. [4]
