Latin

Etymology 1

Unknown, likely a borrowing from an unidentified source.

Compare Old High German linsa, Lithuanian l?šis, Old Church Slavonic ???? (l?šta), and Albanian lend (Proto-Albanian *lenta), sounding too similar for a coincidence, however different enough to prohibit reconstruction of a common PIE protoform. May also be related to Ancient Greek ??????? (láthuros).

If ultimately a non-IE loanword, locating the source is virtually impossible because cultivation of lentil was widespread in the region since the Neolithic.

• (Classical) IPA^(key): /lens/, [????s?]
• (Ecclesiastical) IPA^(key): /lens/, [l?ns]

2. (Medieval Latin) lens
