Toxin

/ˈtɑːksɪn/noun

A poison produced by a living organism, especially by bacteria.

The Greek roots

τόξον
tóxon
bow
+
φάρμακον
phármakon
drug, poison

Literally: bow poison

The story of the word

A bow is hiding inside this word. τοξικὸν φάρμακον was the poison archers smeared on arrowheads, from τόξον, the bow; Latin kept the adjective alone and toxicum came to mean poison outright. Ludwig Brieger trimmed the ending in 1886 to name the poisonous products of bacteria, and the archery has been invisible ever since.
