Etymologies
- Recorded since c.1340, as "discharge of semen other than during sex," later, "desecration, defilement" (1382), from Late Latin pollutio "defilement," from Latin polluere "to soil, defile, contaminate", itself from por- "before" + -luere "to smear" (related to lutum "mud" and to lues "filth", compare Greek (lyma) "filth, dirt, disgrace" and (lymax) "rubbish, refuse," Old Irish loth "mud, dirt," Lithuanian lutynas "pool, puddle"). Sense of "contamination of the environment" first recorded c.1860 (Wiktionary)
