Etymology
Etymology Information

'biocide' originates from combining the Greek prefix 'bio-' (Greek 'bios') meaning 'life' and the suffix '-cide' (from Latin 'caedere') meaning 'to kill.'

Historical Evolution

'biocide' is a modern formation (Neo-Latin/English) created by combining 'bio-' + '-cide' and entered English usage in the late 19th to early 20th century to name agents that kill living organisms.

Meaning Changes

Initially it referred broadly to any agent that kills life; over time it has come to be used specifically for chemical or biological agents used to control harmful organisms and is used in scientific and regulatory contexts.
