anicca: The unstable, impermanent, transient nature of all phenomena in all realms of existence. In other words, all things arise and cease, are subject to change, and will become otherwise, making them all inherently unsatisfactory and bound to cause suffering.

无常(anicca)：不稳定、变化、生灭的性质，是一切层次的存在共有的现象。换句话说，一切生起灭去，变化不居，由于这个特性，使得世人无法满足安住，而成为苦的原因。
