Pronunciation

Forms

olmo m (plural olmos)[1]

Etymology

It is inherited from Old Spanish olmo, inherited from Latin ulmus (“elm”).[2][3][1]

The same Latin word is Portuguese olmo, Catalan om, French orme, Italian olmo and Romanian ulm.[4][1] Other forms in Spain are Aragonese urmo and Asturian omo.[5] The older Catalan form was Old Catalan olm, which gave way from the 15th century on.[6]

De Vaan derives the Latin word from Proto-Italic *elmos through *olmos and compares Old Irish lem and Old Norse almr.[7] Wiktionary takes it back to Proto-Indo-European *h₁élem (“mountain elm”),[1] but de Vaan finds a PIE form hard to reconstruct and suggests that the word, found only in Italic, Celtic, Germanic and Slavic, may come from a non-Indo-European language.[7] It is related to English elm.[1][8]

Earliest recorded meaning

Corominas dates the word to 935, a charter in Oelschläger's list of first records.[2] DEMel's first record is in the Fuero de Lerma of 1148.[9] The Fuero de Alcalá (c. 1235) fines whoever cuts an elm, a willow, a mulberry or a holm oak: esta caloña sea por olmo, e por salze, e por moral.[10]

Semantic evolution

The word has always named the elm tree.[3][9] The proverbial phrase pedir peras al olmo, “to ask the elm for pears”, to expect from someone what they cannot give, is used twice in Don Quijote.[11][12] The Diccionario de Autoridades called the elm a kind of poplar.[12] In Mexico the name also goes to other trees, such as an ulmaceous tree of the genus Chaetoptelea, and in places to the poplar.[13]
