Borrowed from Late Latin circulātus, perfect passive participle of Late Latin circulō (“to make circular, encircle”) (see -ate (verb-forming suffix)), a later collateral form of circulor (“form a circle (of men) around oneself”), from circulus (“a circle”). See also Middle English circulat(e) (“(alchemy) changed by continuous distillation in a closed vessel”).
When used transitively, it requires a direct object (e.g., 'circulate the document').
