Appearings are the visible or evident manifestations of something. Their antonyms are, therefore, words that signify the opposite of visibility or evidence. Words like disappearance, evanescence, invisibility or vanishing are some of the antonyms of appearing. Disappearance, for instance, implies the act or process of vanishing from sight or existence. Evanescence depicts a gradual fading or vanishing away. Invisibility, on the other hand, suggests a state of being hidden or imperceptible to the eye. Finally, vanishing implies a sudden or complete disappearance from sight. Thus, understanding the antonyms of appearing is crucial to understanding the conditions under which things become less visible or cease to exist.
