History
Etymology
From French instant and Middle English instant, both from Old French, from Latin instans (“standing by, being near, present, also urgent, importunate”), present participle of instō (“to stand upon, press upon, urge, pursue, insist”), from in (“on, upon”) + stō (“to stand”); see state.
From Middle English instant (“infinitely short period of time”), from Old French instant (“assiduous, at hand”, adjective), from Latin īnstāns, īnstantis (“present, pressing, urgent”, literally “standing near”), present active participle of īnstō (“to stand upon, be nearby”), from in- (“after”) + stō (“to stand”). Compare Old English instede (“immediately, on the spot, at once”). More at in, stand.
Ultimately from Latin īnstāre; its precise evolution is uncertain. OED hints at (unattested) Middle French *instanter.
