Latin (servō)

Pronunciation

  • Classical: [ɔp.sɛrˈwan.ti.a][1]
  • Ecclesiastical: [ob.serˈvan.t͡si.a][1]

Forms

observantia f (genitive observantiae); first declension[1] Manuscripts also spell it observancia, and an edict of Diocletian has ubservantia.[2]

Etymology

It is from Latin observāns (“observing”) + -ia, the present participle of observō (“to watch, heed, respect”),[3][4][2] which is a compound of ob- and servō (“to keep, watch”).[1]

Earliest recorded meaning

Köbler records it first in Cicero,[4] who defines it as the virtue by which we respect and honour those who surpass us in age, wisdom, rank or other distinction.[3][5]

Semantic evolution

In Cicero it is the respectful regard shown to elders and superiors and the attentions by which friends are kept;[3][5] Livy has it towards a king, and Quintilian of freedmen towards their patrons.[5] Velleius uses it of watching or observing the seasons.[3][5] Valerius Maximus and the jurists use it of keeping laws, customs and rules,[3][5] and in Late Latin it came to mean religious observance and worship, as in the Theodosian Code and the Vulgate.[5] Medieval Latin used it of obeying the law, of a regulation or law itself, and of keeping divine law, religious duties and rites;[6] in Ecclesiastical Latin it also meant abstinence and practice.[7]
