Pronunciation

  • /obseɾˈbaɾ/, [oβ̞.seɾˈβ̞aɾ][1]

Forms

observar (first-person singular present observo, first-person singular preterite observé, past participle observado)[1]

Etymology

It is a learned word, borrowed from Latin observō (“to watch; to heed, comply with”).[2][3][4][1] The Latin verb is formed ob- and servō (“to watch, keep safe”).[1][5][6] Corominas groups it with conservar, preservar and reservar, other learned words of the same Latin root.[2][3]

The neighbouring languages took the same Latin verb: Portuguese observar, Catalan observar, French observer and Italian osservare.[1] French has it from about 980, at first only in the moral sense “to comply with”.[7]

Earliest recorded meaning

Corominas dates the word to the mid-16th century, with Gutierre de Cetina (died 1557) and Ribadeneira.[2][3] The CDH has it much earlier in notarial documents of Aragon, first in a charter of San Juan de la Peña of 1296 that binds the tenants de tenir e de observar totas las ditas cosas “to keep and observe all the said things”; the DEMel cites a document of Upper Aragon of 1264.[8][9] Earlier hits in the CDH, from 1223, are Latin charters.[8] In all these texts the sense is “to comply with” an agreement or a law.[8]

Semantic evolution

The Latin verb meant both “to watch closely” and “to comply with”, and Spanish took over both senses.[3] Nebrija's Latin dictionary (1492) glosses Latin observo as acatar and guardar “to respect, keep”.[10] The Diccionario de Autoridades puts the sense “to watch attentively and reflect on” first, then “to keep and fulfil exactly what is ordered”, and adds the astronomical sense of following the movements of the stars with instruments.[11] Terreros added the sense “to notice, perceive”.[12] The DLE keeps these four senses, the last being “to watch discreetly, spy on”.[4]
