Forms

obsidātus m (genitive obsidātūs); fourth declension[1][2]

Etymology

It is from Latin obses (“hostage”) + -ātus, formed like praesidātus.[3][1]

Earliest recorded meaning

It first appears in Ammianus Marcellinus, of a father long held “by the pledge of hostageship” (diu obsidatus pignore tentus).[1][3][4]

Semantic evolution

Lewis & Short class it as post-classical.[1] Besides Ammianus it occurs in the scholia on Juvenal, of someone “given in hostageship”.[1][2] In Medieval Latin it kept the sense of the position of a hostage and could also mean the hostages themselves.[5] The manuscripts also have the spelling obsedatus.[3]
