Pronunciation

Forms

fournaise f (plural fournaises)[1] Old French fornaise, forneise, beside the rarer masculine fornais, fornaiz.[2][3][4][5] The spelling fournaise appears in the 16th century.[3]

Etymology

It is inherited from Old French fornaise, a remaking with a feminine ending of Old French fornais, inherited from Latin fornāx (“oven, kiln”).[2][6][1][7] The Old French masculine is poorly attested; the TLFi thinks it was probably feminine, like the Latin word and most of its Romance outcomes, while Bloch and Wartburg call it masculine but of hesitating gender.[2][6] The Latin word is related to furnus (“oven”), of which the Robert dictionaries call it an augmentative.[8][9][4]

Cognate with Italian fornace, Spanish hornaza and Old Occitan fornaiz.[6][4] French four and fourneau come from the same Latin family.[5]

Earliest recorded meaning

It is first recorded about 1121 in the Voyage of Saint Brendan (Cume buche de fornaise), meaning a large oven with a fierce fire.[2][5]

Semantic evolution

The first sense, a large oven or furnace, has gone out of use.[5][9] By metonymy the word was used for the fire of hell (about 1190, Marie de France) and for any blazing hearth, as in la fournaise du mont Etna (1654).[5][3][2]

By analogy it came to mean a very hot place (1823) and, as a metaphor, a centre of intense activity (about 1830, Hugo), a development Rey compares with that of ébullition.[5][2] The GLLF dates the sense “battlefield, scene of fierce fighting” to Hugo in 1853.[3] In Canada, under the influence of the English word, it names a central-heating boiler (19th century), a use the Petit Robert marks as criticized.[9][10]

The Old French word had already passed into English as furnace (early 13th century).[11]
