Coming to or arriving at; approaching or imminent (archaic or poetic usage).
From Latin 'adveniens,' present participle of 'advenire' (to come to). Used poetically in older English literature to describe something approaching or about to occur.
Poets used 'advenient' to build suspense—'the advenient storm' gave the feeling of something powerful and unstoppable drawing near, a quality lost when we switched to simpler words like 'coming.'
