This list is primarily dedicated to all the world wide students asking me to provide them with short and long adjectives as well as adjectives that start with a letter of alphabet or another. I didn't get the point behind their requests and I never asked; but I'm trying to provide them with a series of adjectives to enrich their vocabulary repertoire, to vary their diction; and make their language affluent, fluent and wide-ranging..
