Lexico-semantic variant of the word is every meaning of a polysemantic word with reference to what it denotes in the extra-linguistic world (referential meaning) and with respect to the other meanings with which it is contrasted in the semantic structure (differential meaning).
The lexical meaning is a complex phenomenon and may be analysed as including denotational and connotational components.
The denotational meaning is the component of the lexical meaning which makes communication possible because the knowledge people have about things is ultimately embodied in words which have essentially the same meaning for all speakers of that language.
