*lēþą

Disputed. Suggested as cognate with Ancient Greek λάτρον (látron) (látron, ‘payment’) and Latin latrō (‘mercenary’), from Proto-Indo-European *leh₂t- (‘to grant; to possess’), but the vowel correspondences are irregular. Perhaps alternatively from *leh₁-t-, extended from *leh₁- (‘to let’) (whence also Proto-Germanic *lētaną, from a different extension *leh₁-d-).

Beekes rejects an Indo-European etymology entirely and considers the purported Greek cognate to be from Pre-Greek, whereas the Latin is borrowed from Greek.
