Semantics
Etymology
From Greek sēmantikos, "significant, having meaning," from sēmainein ("to signify, show"), from sēma ("sign, mark"). The French linguist Michel Bréal coined sémantique in the 1880s for the science of meaning, and English borrowed it around 1900. The dismissive phrase "just semantics" is a later twist — treating a genuine dispute about meaning as if it were mere hair-splitting.
noun · /sih-MAN-tiks/
The study of meaning in language — how words and sentences relate to the ideas and things they stand for.
What it names
A precise label for the layer of language that is about meaning itself, separable from how sentences are built or how they’re used in practice.
Example
Whether a hot dog is a "sandwich" is a question of semantics, but the argument gets surprisingly heated.
Related idea
Pragmatics studies meaning that depends on context and speaker intent; semantics studies the meaning words carry on their own, before anyone speaks them.
noun · /sih-MAN-tiks/
Petty quibbling over the exact meanings of words, treated as a distraction from the real issue.
What it names
arguments that turn on word choice rather than substance
Example
Whether you call it a bug or a defect is just semantics.
Related idea
This dismissive sense inverts the serious study of meaning; compare pragmatics, which looks at meaning in context.
