If you are incommunicado you are out of touch, unable to be communicated with, or in an isolated situation. An introvert is one who primarily prefers being by himself instead of hanging out with others socially. An irascible person becomes angry very easily. A laconic person uses very few words to say something. If you describe someone as loquacious you mean that he talks too much.
