Etymology

It is from earlier fornus, inherited from Proto-Italic *χworno-, inherited from Proto-Indo-European *gʷʰr̥-no- (“heat, oven”), from the root Proto-Indo-European *gʷʰer- (“to be hot”).[2][1] Cognate with Old Irish gorn (“fire”), Sanskrit घृण (ghṛṇá, “heat, glow”) and Russian горн (gorn, “blacksmith's hearth”).[2][3][4] The raising of /or/ to /ur/ before a consonant was going on in part of Roman speech, perhaps under dialect influence, since it is regular in Sabellic.[2] It is related to fornāx “furnace” and formus “warm”.[2][3]

Earliest recorded meaning

De Vaan dates furnus from Plautus, who also has fornus, as Varro does.[2][3] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant an oven, as Plautus' joke about being put in a hot oven and roasted like a loaf, and a bakehouse, as in Horace and Juvenal.[3][6] Seneca and Pliny the Elder also use it.[7] Lewis and Short give camīnus and clībanus as synonyms.[6]

In Medieval Latin it also meant a stove.[8] It survives in Italian forno, French four and Spanish horno.[1] English furnace comes from fornāx through Old French, recorded in the early 13th century.[9]
