Pronunciation

Forms

fétu m (plural fétus)[1] Old French festu.[2][3]

Etymology

It is inherited from Old French festu, inherited from Late Latin festucum, a Late Latin variant of Latin festūca (“stalk, blade of straw”).[4][5][6][7] The Latin noun also meant, by antiphrasis, a rammer for driving in stakes.[6]

Cognate with Italian festuca and festuco, Old Occitan festuga and festuc, which continue both Latin forms,[7][2] and with Walloon fistou.[2] The learned fétuque “fescue” is a later borrowing of the Latin word.[6] English fescue comes from the Old French form.[3]

Earliest recorded meaning

It is first recorded about 1170 in Chrétien de Troyes's Erec, as a straw used figuratively for a thing of little worth.[4][6] The GLLF dates it to the early 12th century, in the Pèlerinage de Charlemagne.[8]

Semantic evolution

French kept the Latin sense “straw” and also used it from the start for something light or worthless.[6][4] Old French phrases built on it include ne pas donner un fétu (1273, Adenet) and rompre le festu, breaking a straw to mark the end of a bond or a pledge;[8][3] Littré also records tirer au court fétu, for which tirer à la courte paille was already preferred.[2] The ironic sense of the iron bar with which the executioner broke condemned men on the wheel is dated 1576 by Esnault.[8][2]

In the 18th century fétu was a botanical term, later replaced by fétuque (1775).[6] Today it is mostly found in fétu de paille and in emporté comme un fétu.[9][8]
