Definition of the word live by

The phrase "live by" has its origins in the Old English language, specifically in the preposition "by," which meant "near" or "close to." The Old English word for "life" was "lyf," which evolved into the Middle English "lue." In early English, the expression "live by" was used to convey the notion of living in close proximity to something, such as a body of water, "living by the sea." But over time, it began to take on a more figurative meaning. In the 14th century, Chaucer used the phrase "loupen by the syde of," which means "live close to," but by the early 1500s, it was being used to denote an allegiance or adherence to something, as seen in William Turton's text "The Popes Supplication": "And knowing hereby that you loue her by the loyallnese of your heartes." The modern-day usage of "live by" is a result of this evolution, as it implies a strong reliance or dependency on something, be it a set of values, principles, or beliefs. It conveys a sense of alignment and commitment, and is often used in discussions about lifestyle choices, religious or moral convictions, and other major contributing factors to an individual's identity.
