Etymology

The word "instant" traces back to Latin instans (present participle of instare, "to stand upon or urge"), combining in- (upon) + stare (to stand). It originally conveyed urgency ("pressing upon") and evolved to emphasize immediacy in time ("happening at once"). The food sense emerged in the 20th century with processed convenience products.
