Etymology

It is borrowed from Ancient Greek σηπτικός (sēptikós, “putrefactive”).[1][2][3][4]

Earliest recorded meaning

Pliny the Elder has it of remedies that cause flesh to decay: horse's blood, he says, eats away flesh septica vi, “by its putrefying power”.[2][4]

Semantic evolution

In Latin it is a rare technical word of medicine, said of substances that are corrosive or cause putrefaction.[2][3][5] Pliny uses it in several places in the Natural History.[2][3] Through it English took the word septic around 1600, later used especially of infections.[6]

Usage notes

At one of Pliny's passages Jahn's edition reads smecticus instead.[3]
