Antiseptic
an-tih-SEP-tik
/ˌæn.tiˈsɛp.tɪk/
A substance that prevents the growth of disease-causing microorganisms on living tissue.
Used specifically on living tissue (like skin or wounds), distinguishing it from household disinfectants used on non-living surfaces.
The story behind the word. Antiseptic fuses Greek 'anti-' (against) with 'sepein' (to rot or decay). Prior to the 19th century, wound infections were viewed as inevitable decay. British surgeon Joseph Lister demonstrated that carbolic acid could stop this rotting process, launching the modern era of antiseptic surgery.
Word relationships

- septic: Septic describes tissue infected with micro-organisms or toxins.
- contaminant: A contaminant introduces disease or infection to a clean area.

Memory hook
ANTI (against) + SEPTIC (sewage/rot) = standing against rot and infection! Guarding wounds against infection and decay.
When not to use
Do not use for household counter cleaners; chemical cleaners for tables are disinfectants or sanitizers, not antiseptics.
Fun facts
- Listerine mouthwash was named in 1879 in honor of Joseph Lister and was originally used as a floor cleaner and cure for gonorrhea before being marketed for bad breath!
- Honey was used as a natural antiseptic in ancient Egypt because its high sugar content draws water out of bacterial cells.
