lutum

From Proto-Indo-European *lew- (“dirt, mud”). Cognate with Old Irish loth (“mud”), Ancient Greek λῦμα (lûma, “dirt, filth”), Albanian lym (“mud”), Lithuanian liutýnas (“loam pit”).^[1]

• lutus

• (Classical Latin) IPA^(key): [ˈɫʊ.tũː]
• (modern Italianate Ecclesiastical) IPA^(key): [ˈluː.t̪um]

lutum n (genitive lutī); second declension

1. soil, dirt, mire, mud

   Synonyms: caenum, sordēs

2. loam, clay

Second-declension noun (neuter).

Unknown. Maybe from Old Latin clūtum (/⁠glūtum^?⁠/), from an extended form of Proto-Indo-European *ǵʰelh₃- (“green, yellow”) (compare Latin fel, helvus, holus), but the required suffixation of the root would be unusual. More likely from a substrate source along the lines of *(w)lut- related to the source of Proto-West Germanic *waldu (“dyer's weed”) (< *wolt-).
