The word semantics comes from Greek roots that mean “having meaning” or “signifying.” Etymologically, semantics refers to the study of meaning, especially in how words, phrases, symbols, and sentences convey sense in language. It examines not only definitions, but also the relationships, contexts, and interpretations that give rise to meaning.
Etymological Breakdown:
1. Greek: semantikos (σημαντικός)
- Meaning: “significant,” “having meaning,” “indicating”
- From:
- semaino (σημαίνω) = “to signify,” “to mean,” “to point out”
- Derived from:
- sema (σῆμα) = “sign,” “mark,” “signal,” “token,” “symbol”
- Derived from:
- semaino (σημαίνω) = “to signify,” “to mean,” “to point out”
In ancient Greek, sema referred to:
- A physical marker (like a grave marker or symbol)
- A signal or signifier of deeper meaning
2. Greek Root: semaino
- Meaning: “to make known,” “to signal”
- Verb formed from sema = “sign”
- Related to PIE root **dhe- or **sem- = “to assign,” “to point out,” “to mark”
3. Modern Use: semantics (1890s–early 20th century)
- Coined as a branch of linguistics and logic
- Focuses on the interpretation of signs and meanings
- Gained prominence in philosophy, linguistics, computer science, and semiotics
Literal Meaning:
Semantics = “That which pertains to signification or meaning”
→ The study or analysis of meaning, especially how language communicates sense and how symbols refer to reality or concepts.
Expanded Usage:
1. Linguistics:
- Lexical semantics: Meaning of words and vocabulary
- Compositional semantics: How meanings combine in phrases/sentences
- Pragmatic semantics: Meaning in context and use
2. Philosophy of Language:
- Explores how meaning relates to truth, reference, and understanding
- Questions how language refers to real or abstract entities
3. Semiotics and Logic:
- Formal semantics: Symbolic meaning in logical systems
- Semantic analysis: Dissecting meanings systematically
4. Computer Science / AI:
- Semantic web: Structuring data meaningfully for machines
- Semantic search: Interpreting queries by meaning, not keywords
5. Common / Informal Use:
- “It’s just semantics”: Dismissing a debate over words instead of substance
- Semantic drift: Change in meaning of a word over time

Metaphorical Insight:
Semantics is the science of sense—the effort to understand how form becomes meaning, how sound and symbol make thought visible, and how language points beyond itself. It is the architecture of interpretation, the bridge between sign and understanding, and the canvas on which human intention becomes shareable.
