Etymology

The word "during" originated from the Old French durant, the present participle of durer (to last), which itself derives from Latin dūrāre (to harden, endure). Over time, the sense shifted from "lasting" to "throughout the duration of," reflecting its modern prepositional use. The suffix -ing marks its grammatical role as a participle-turned-preposition.
