Forms
lac m (oblique plural las; nominative singular las)[1]
Etymology
It is borrowed from Latin lacus (“tub, basin; lake”).[1][3][4][5] The inherited form of the same Latin word was lai, which had little vitality and was displaced by the borrowing.[3][6][5] The FEW and the TLFi allow that the sense “pit” may also have come north from Old Occitan lac.[5][7]
The Latin word continues Proto-Italic *laku- and Proto-Indo-European *lok-u- (“lake”), whose cognates include Old Irish loch, Ancient Greek λάκκος (lákkos, “pond”) and Old English lagu.[8] Its Romance continuations include Italian lago, Spanish lago and Romanian lac.[9] Wiktionary adds that early Middle English lac may have helped it displace the inherited form.[1]
Earliest recorded meaning
The first record is the Cambridge Psalter, an Anglo-Norman interlinear translation of the first half of the 12th century, where the word means a pit.[5][10][11] Bloch–Wartburg and the DHLF date it about 1120, and the DHLF ascribes the sense “pit” to Christian Latin.[3][4]
Semantic evolution
The sense “lake” is recorded from Chrétien de Troyes's Erec et Enide, 1165–1170, which names Lanceloz del Lac.[5][12] The sense “pit” lasted into the 14th century, in Guillaume de Machaut's lac aus lyons, the lions' den of Daniel.[5][13] The AND also records the pit of Hell and a wine-vat or wine-press, perhaps from a misreading of lacus in Revelation.[2] The word survives as French lac.[5]
Timeline
- 1100–1150 – lac “pit” in the Cambridge Psalter.[5][10][11]
- c. 1120 – the date Bloch–Wartburg and the DHLF give.[3][4]
- 1165–1170 – “lake” in Chrétien de Troyes's Erec et Enide.[5][14]
- c. 1225 – lac in the prose Queste del saint Graal.[15]
Meanings

Anglo-Norman
The AND heads the word lac, first cites it from the first half of the 12th century, and lists lach, lak and lake.[2] It has a separate article for the inherited lai in the same senses, first cited in the third quarter of the century.[17] Middle English lake continues Old English lacu and was reinforced by Latin and by the Old French word.[18][19]
Descendants
- Middle French lac (→ French lac)[1][5]
- Norman lac[1]
- Middle English lake (partly borrowed; → English lake)[18][19]
