Why did Charles Sanders Peirce argue that a sign’s meaning must be continuously qualified?

Charles Sanders Peirce argued that a sign’s meaning must be continuously qualified because he maintained that a sign can never possess a single, fixed, or definitive meaning.1

Peirce, a founder of semiotics, defined a sign as "something which stands to somebody for something". Because his work was deeply rooted in pragmatism and the logic of science, he viewed the process of semiosis—or sign action—as dynamic rather than static. By emphasizing that meaning is subject to continuous qualification, Peirce highlighted the evolving nature of interpretation and the way signs function within a system of relations, rather than as isolated, immutable entities.12
