How language works as a system of arbitrary symbols, why words never mean exactly one thing to everyone, and how the language we use shapes—and is shaped by—power, culture, and thought.
Language is a structured system of symbols that people use to communicate. Human language has several defining characteristics that distinguish it from other communication systems:
Because language is symbolic, meaning does not live inside a word—it is constructed by the people using it. Two important distinctions help explain this:
Meaning is also shaped by whether language is used concretely (specific, tangible, low-inference: "a 2019 red Honda Civic") or abstractly (general, vague, high-inference: "a car"). Concrete language reduces misunderstanding because it leaves less room for varied interpretation.
Communication scholars have long debated how closely language and thought are linked. The Sapir–Whorf hypothesis proposes that the language we speak shapes—and even limits—the way we think and perceive reality, because we can only easily conceptualize what we have words for.
Language is also central to cultural identity. The vocabulary a culture develops often reflects what that culture considers important (for example, some languages have many distinct words for concepts that English collapses into one general term), and losing a language can mean losing part of a culture's collective knowledge and worldview.
Language is never neutral—the words we choose (or are permitted to use) reflect and reinforce social power relationships.
