The phrase "hath no end" is often used to denote something that is eternal or infinite. Some synonyms that can be used instead of this phrase include "never-ending," "endless," "boundless," "infinite," "perpetual," and "unceasing." These words are commonly used to describe things that seem to go on forever, such as love, time, or the universe. Using these synonyms can add variation and depth to writing and help to convey a sense of magnitude and transcendence. Whether one uses "hath no end" or any of its synonyms, the message remains the same: there are some things that are simply beyond measure, beyond time or space, and beyond our understanding.
