• (Classical Latin) IPA^(key): /ˈlae̯.tus/, [ˈɫ̪äe̯t̪ʊs̠]
• (modern Italianate Ecclesiastical) IPA^(key): /ˈle.tus/, [ˈlɛːt̪us]

Unknown; possibly related to alacer (“happy, glad, cheerful”).^[1] Often compared to lardum (“fat, bacon lard”) and largus (“abundant, bountiful”),^[2][3] presupposing an earlier form *lai-to and earlier *lai-es, but de Vaan finds this reconstruction problematic.^[4]
