Some terms related to "meaning" in semantics are reviewed, particularly those used in Lyons' famous semantics book Semantics 1 and Semantics 2 (Cambridge University Press, 1977). Since Lyons' book is so comprehensive that the semantic terms used in that book cover almost every important notions/terms used in contemporary semantics. With relevant interpretation of the terms, we suggest most appropriate Korean translations, trying to give different translations for different English terms. Terms covered include: 'signify, signification; reference/refer/referent, sense; denotation/denote, connotation/connote; extension, intension; implication/imply, implicature/implicate, entailment/entail; designate, demonstrate/demonstrative'.
