Ludwig's WRAP-UP
The term "unchanging" functions primarily as an adjective to denote something that remains constant and stable. According to Ludwig, it is grammatically correct and widely used. Its communicative purpose is to emphasize permanence and the absence of change, often in formal and scientific contexts, though it is also prevalent in news media. While alternatives like "constant" or "immutable" offer similar meanings, "unchanging" is especially useful for highlighting a lack of alteration over time, as illustrated by examples from authoritative sources like The Economist and Stanford Encyclopedia of Philosophy.
