The word "un-real" means something that is not real or exists only in the imagination. Its antonyms would be "real," "genuine," "authentic," "natural," "actual," and "true." These words describe something that is tangible, factual, and can be experienced through our senses. Real means something that is authentic and accurately represents itself, while genuine refers to something that is honest, sincere, and without any artificiality. Authentic describes something that is true to its nature, while natural means something that occurs without any human influence. Actual describes something that is currently present, and true means something that is valid and accurate. All these words are opposite to the meaning of "un-real" and help describe something that is credible and reliable.
