mortem sibi consciscere

Etymology:

• se interficere, se occidere, se necare are rare. During the classic period, when suicide was not common, ipse is often added—e.g. Crassum se ipsum interemisse (Cic. Scaur. 2. 16), Lucretia se ipsa interemit (Fin. 2. 20. 66); but later, when suicide had become frequent, se interemit; nonnulli semet interemerunt (Suet. Iul. 89), etc., occur commonly.
