Where this word comes from
Per De Vaan (2008), from Proto-Indo-European *l(H)u-(s)tro- (“dirty place”), from Proto-Indo-European *le(H)w- (the same root as lutum (“mud, dirt, clay”)) + *-trom (see -trum), compare lūstrum, flū̆stra and mōnstrum. Valpy (1828) proposed instead a borrowing, with change of *d to /l/, from Ancient Greek *δύστρον (*dústron), from δύω (dúō, “to plunge”).
a purificatory sacrifice (expiatory offering) or lustration performed every five years by the censor
a period of five years
Where this word comes from
From Old Latin *loustrom, of uncertain origin, with multiple theories proposed: * from Proto-Indo-European *lewkstrom, from *lewk- (“to make bright”) (whence lūceō), * or from Proto-Indo-European *lewh₃strom, from *lewh₃- (“to wash”) (whence lavō), * or from Proto-Indo-European *lewHstrom, from *lewH- (“to expiate, set free”) (whence luō). Compare lustrum, flū̆stra and mōnstrum.
