Etymology

It is from inter- “between” and claudō “to shut”.[2][1] De Vaan traces ⟨claudō⟩ to Proto-Indo-European *kleh₂u-d- (“to shut”).[3]

Earliest recorded meaning

The OLD's earliest citation is from the Rhetorica ad Herennium, of blocking a road.[2] Köbler dates it 86/82 BC.[4]

Semantic evolution

It meant to make impassable, block, cut, as of roads, the sea or a flight in Caesar; to choke, stifle the breath or voice, as in Varro; to separate, cut off from; to cut off someone's advance or passage; to prevent a person from acting; and to hinder, obstruct, all in Cicero.[2][5]

In Ecclesiastical Latin it meant to block, hinder, shut off.[6] British Medieval Latin glossaries misread it as a noun, a screen, barrier.[7]
