Forms
obses m or f (genitive obsidis); third declension[1] The old spelling opses appears in the first epitaph of the Scipios.[2][3] Caesar and Livy have the genitive plural obsidium.[3]
Etymology
It is formed from ob- (“before, against”) and the root of sedeō (“to sit”), as ⟨*ob-sed-s⟩; the TLL takes it from obsideō (“to sit by, occupy”), comparing praeses from praesideō.[2][4][1] De Vaan lists it among the derivatives of the simple verb, which he traces to Proto-Italic *sed-ē- (“to be seated”) and Proto-Indo-European *sed-eh₁-, cognate with Ancient Greek ἕζομαι (hézomai, “to sit down”), Gothic 𐍃𐌹𐍄𐌰𐌽 (sitan, “to sit”) and Old Church Slavonic сѣдѣти (sěděti, “to sit”).[5]
Earliest recorded meaning
The epitaph of Lucius Cornelius Scipio Barbatus says that he subdued all Lucania and led away hostages: subigit omne Loucanam opsidesque abdoucit.[2][3]
Semantic evolution
An obses is a hostage, a person handed over as a pledge that a treaty will be kept.[2][1] By extension it is any surety or guarantee, of persons (Cicero says the republic embraces a man as a hostage of his consulship) and of abstract things (Cicero: the Roman people hold many pledges from us).[2] It is masculine, rarely feminine.[4][2]
Church Latin glosses it “hostage”;[6] in medieval Latin it is also a security or bail, a guarantor, and a hostage given under a contract.[7]
