Etymology

It is inherited from Proto-Italic *mormīkā-, inherited from Proto-Indo-European *moru̯-o/ī̆- (“ant”).[2][1] The word for “ant” has many irregular forms in the Indo-European languages, probably from taboo distortion, as still happens in Dutch and German dialects.[2] The Latin /f/ may come from /m/ by dissimilation of /m…m/ to /f…m/.[2][1]

Cognate with Old Irish moirb (“ant”), Welsh myr (“ants”), Sanskrit वम्र (vamrá, “ant”), Avestan maoiri- (“ant”) and Ancient Greek μύρμηξ (múrmēx, “ant”).[2][3]

Earliest recorded meaning

It is found from Plautus onwards,[2][4] who threatens to have someone torn to pieces bit by bit by ants.[5]

Semantic evolution

It always meant “ant”, and Cicero, Virgil and Horace mention it.[5][6] Suetonius mentions winged ants.[6]

Servius, followed by Isidore of Seville, derived the name from the ant's carrying crumbs, micas ferre, an ancient guess.[7] It survives as Italian formica, Spanish hormiga, Portuguese formiga and Romanian furnică, and English formic (acid) was coined from it in 1791.[1][8]
