Forms

observāns (genitive observantis, comparative observantior, superlative observantissimus); third-declension adjective of one termination[1][2]

Etymology

Used as an adjective, it is the present participle from Latin observō (“to watch, observe”).[1][3] That verb is a compound of ob- and servō (“to watch over, keep”).[1] De Vaan reports Rix's view that the simple verb was made from an old noun Proto-Italic *serwā- or *serwom (“observation”), related to servus, which goes back to Proto-Indo-European *ser-u-o- (“guardian”).[4] Cognate with Avestan haraiti (“heeds, protects”).[4]

Earliest recorded meaning

Cicero is its first author.[3] In the Pro Quinctio he speaks of a relative who is attentive to the man addressed, hominem propinquum, tuī observantem, and in a letter to his brother he promises that he will find someone grateful and attentive, grātum hominem observantemque.[1][5]

Semantic evolution

It meant attentive and respectful towards someone, often with a genitive, as in Cicero's letters (observantissimum studiōsissimumque nostrī) and in Pliny the Younger.[1][2] It also meant scrupulous in carrying out one's duties: Pliny the Younger tells a correspondent that he is omnium officiōrum observantissimus, and Gellius notes that religiōsus came to be used for someone chaste and observant.[1][5] Apuleius uses it of the stars keeping a very exact law in their courses.[1][2]

Church Latin also used it as a masculine noun, Observant.[6] It survives in Italian osservante.[5]
