Pronunciation

  • /ʝaˈθeɾ/, [ɟ͡ʝaˈθeɾ], /ʝaˈseɾ/[1]

Forms

yacer (first-person singular present yazco or yazgo or yago, first-person singular preterite yací, past participle yacido)[1] Old Spanish wrote yazer, iazer and yaser.[1][2][3] Its old strong preterite was yogo (subjunctive yoguiere); a misreading of it as yogó gave rise to an infinitive yogar.[4][3]

Etymology

It is inherited from Old Spanish yazer, inherited from Latin iaceō (“to lie”).[5][6][1] The same Latin verb is Portuguese jazer, Catalan jeure (older jaure), French gésir, Italian giacere and Romanian zăcea.[4][1][7] In Ribagorza the form is Aragonese chase.[8]

The Latin verb is the stative counterpart of iaciō (“to throw”): “to lie” was first “to be in the state of a thing thrown”.[9][1][10] De Vaan traces both verbs to a root Proto-Indo-European *(H)ieh₁- (“to throw, let go”), the root of Ancient Greek ἵημι (híēmi, “to send, throw”).[9]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) has the verb in the sense “to lie, to rest for the night”: Esta noch yagamos e váimosnos al matino, “let us lie here tonight and leave in the morning”.[11][5] The Auto de los Reyes Magos (c. 1180) asks whether something lies in the scriptures (si iace in escripto).[11]

Semantic evolution

Old Spanish used the verb for lying down, for a body lying in the grave, for a thing being in a place, and for sleeping with a woman.[12][11] Alfonso X's General estoria (1280) says that an epitaph should give the name of the one who lies there (el nombre del qui yaze alli).[12] After the 15th century the verb became rare.[5]

Autoridades (1726–1739) defines it as lying stretched out, used properly of the dead, and notes forms with g such as yago and yazga; it quotes the Quijote: donde yago tan molido.[13] Terreros gives the epitaph formula aquí yace.[14] The Academy's dictionary of 1817 marks the sexual sense as old, and that of 1884 adds horses grazing in the fields at night.[15][16] The derivative yacimiento “deposit (of minerals)” dates from about 1900.[5]
