Why is the ninth month called September?
early 15c., from Latin laceratus, past participle of lacerare "tear to pieces, mangle," figuratively, "to slander, censure, abuse," from lacer "torn, mangled," from PIE root *lek- "to rend, tear" (cf. Greek lakis "tatter, rag," lakizein "to tear to pieces;" Russian lochma "rag, tatter, scrap;" Albanian l'akur "naked"). Related: Lacerated; lacerating.
