What the thing is
Semiotics is the study of signs.
Where it came from
It emerged as an independent field in the late 19th and early 20th centuries through Peirce and Saussure—but the term and concept predate them by two centuries. The Greek root σημειωτική was linked to disease symptoms. Locke named it for sign-study in 1690. The English word first appeared in the 1670s.
What it gets right
It names and separates three core functions of signs: structure (syntactics), meaning (semantics), and use (pragmatics). It includes maps and clothing—not just words—as legitimate objects of study.
What it gets wrong
It overstates its own novelty. The term appeared in English in the 1670s. Locke proposed it for sign-study in 1690. Its roots are not late-19th-century; that is when it became institutionalised, not born.
Why it matters now
Because every interface, logo, algorithmic feed, and policy document operates via signs. Semiotics gives tools to dissect how meaning is assigned, withheld, or weaponised—without assuming language is the only channel.
Is it worth your time
Yes—if you work with signs, design meaning, or decode culture. No—if you expect quick answers to ‘what does this mean?’
