Lets Know The Polysemy



Polysemy is the association of one word with two or more distinct meanings. A polyseme is a word or phrase with multiple meanings. Adjective: polysemous or polysemic. In contrast, a one-to-one match between a word and a meaning is called monosemy. According to William Croft, "Monosemy is probably most clearly found in specialized vocabulary dealing with technical topics" (The Handbook of Linguistics, 2003).

     According to some estimates, more than 40% of English words have more than one meaning. The fact that so many words (orlexemes) are polysemous "shows that semantic changes often add meanings to the language without subtracting any" (M. Lynne Murphy, Lexical Meaning, 2010).



      Polysemy also mean is the existence of several meanings for a single word or phrase. The word polysemy comes from the Greek words πολυ-, poly-, “many” and σήμα, sêma, “sign”. In other words it is the capacity for a word, phrase, or sign to have multiple meanings i.e., a large semantic field. Polysemy is a pivotal concept within the humanities, such as media studies and linguistics.
A word like walk is polysemous:
She walks the tower (to haunt a place as a ghost).
The workers threatened to walk (to go on strike).
Walk with God! (to live your life in a particular way)

Semantic Structure of Polysemantic Words
     Synchronically, the problem of polysemy ie the problem of interrelation and interdependence of different meanings of the same word. The semantic structure of a polysemantic word is the sum total of relations between its lexico-semantic variants.
The analysis of the semantic structure of a polysemantic word is based onthe following set of oppositions:
1. Direct-derived meaning: rat – animal like, but larger than a mouse; rat –cowardly person; strike-breaker.
2. Extended-restricted meaning: to knock – strike, hit; to knock – of a petrol engine – make a tapping or thumping noise.
3. Free-bound meaning: hat – cover for the head; hat – nonsense (to speak through one’s hat).
4. General-specialized meaning: case – instance or example of the occurence of smth; case – (med.) person suffering from a disease.
