Proto-Celtic

Etymology

Matasović, Pokorny, and the GPC assume the senses "beverage" and "swamp" share an etymology.^[1] Irslinger breaks with this tradition by positing that they have separate etymologies.^[2]

Cognates identified by Pokorny (which he unites under a root *lat-) include Old High German letto (“silt”), Icelandic leðja (“mud”), Ancient Greek λᾰ́τᾰξ (látax, “drop of wine”), and Latin latex. Matasović rejects any relation to the Greek and Latin words.
Matasović, due to struggling to etymologize the *a in this word, assigns substrate origin.
Irslinger posits two possible Indo-European root origins for the "beverage" sense, Proto-Indo-European *pleh₁- (“to fill”) and *leh₂- (“to pour”), preferring the latter root. For the sense "swamp", she maintains the comparisons to Old High German letto (“silt”) and Icelandic leðja (“mud”) but assigns no further etymology to them.
