Forms
obsequiōsus (feminine obsequiōsa, neuter obsequiōsum); first/second-declension adjective[1] It is also spelled opsequiōsus.[2]
Etymology
It is formed from Latin obsequium + -ōsus, an adjective “full of compliance”.[2][1] The TLL compares imperiōsus from imperium.[3] Obsequium “compliance” is from obsequor (“to yield, comply”),[1][4] a compound of sequor (“to follow”), which goes back to Proto-Italic *sekʷ-e/o- and Proto-Indo-European *sekʷ-e/o- (“to follow, accompany”).[5]
Earliest recorded meaning
Its only Classical instance is in Plautus' Captivi, where a speaker says that the other was always as obliging to him as a slave would be (obsequiosus mihi semper fuisti).[3][6][7][8]
Semantic evolution
L&S counts it among the ante-classical words, citing only Plautus.[7] Later Latin has the comparative adverb obsequiōsius in Verecundus, of servants obeying the will of their master.[3]
In British Medieval Latin it meant obedient and compliant, said of a servant or messenger, of the will and of deeds: Osbern of Gloucester glosses it as “full of compliance”, and Thomas Bekynton writes in 1439 of a faithful and very obliging messenger.[9]
