Pronunciation

  • Brazil: /ˈfẽ.nu/[1]
  • Portugal: /ˈfe.nu/[1]

Forms

feno m (plural fenos)[1] Old Galician-Portuguese had feo, fẽo;[2][1] feno is recorded from the 14th century.[2][1] A prazo of 1525 still writes feeno.[3]

Etymology

It is inherited from Latin fēnum (“hay”), first written Old Galician-Portuguese feo, also with a tilde over the e.[2][4][1] The modern form keeps the Latin /n/ that Galician-Portuguese normally lost between vowels: Nascentes calls it a remade form, Aurélio a learned one, and Wiktionary suggests a borrowing from or influence of Asturian fenu, perhaps to avoid a clash with the old word for “ugly”, today feio.[4][5][1] The old form survives in place names such as ⟨Fial⟩ and ⟨Fiais⟩, and the REW records a dialect form ⟨feio⟩ “dry pine needles”.[6][7]

The same Latin word is Galician ⟨feo⟩, Spanish heno, Catalan fe, French foin and Romanian fân.[1][8] Italian fieno was influenced by flore.[7]

The Latin word alternates with faenum.[9][1] If ⟨fē-⟩ is the original spelling, de Vaan derives it from Proto-Indo-European *dʰeh₁-no- (“yield”), from the root of “to suckle”; if ⟨fae-⟩ is older, the etymology is unknown.[9][1]

Earliest recorded meaning

Houaiss dates feo to the 13th century from Cunha's medieval index.[2] The modern form appears in the Horto do Esposo, copied between 1390 and 1437, where feno occurs repeatedly.[10]

Semantic evolution

Since the Latin–Portuguese dictionaries of the 16th century the word means meadow grass cut and dried as fodder.[11][12] In northern Portugal it also means dry pine needles: Viterbo quotes a prazo of 1525 with sseis ffeixes de feeno “six bundles of feeno” in this sense, and the DLP labels the use as Minhoto.[3][13] Morais records the proverb traz feno no corno “he carries hay on his horn”, said of a dangerous person, after the hay tied to the horns of oxen that gored.[14] Botanists use it for sweet vernal grass, feno-de-cheiro.[2][15]
