بررسی نقش های معنایی در هر یک از تفکیک های معنایی فعل «دیدن»

Polysemy is believed by some linguists to be a situation in which a word has several distinct senses (e.g. Koskela and Murphy (2006)). Other linguists, like Antunano (1999) define polysemy as a situation in which a word has several related senses. In this article, both definitions of a polysemous word is considered; polysemy is known a situation in which a word has several senses which are either related or distinct. It is important why a word sense spreads  from its original domain to other domains, more importantly; however, is how two distinct domains relate to each other. For instance, how the “understanding” domain can relate to the “receiving sounds by ear” domain and become different senses of the word “hear”. This article discusses the polysemy of the verb “didæn” along with the theta roles of the subject in each of meaning classes. To do so, all the senses of “didæn” are studied from Sokhan Dictionary (Anvari, 1387), Dehkhoda Dictionary, Dictionary of Persian Collocations (EslamiShoar et al, to be published), and Madarshahian (1388). All the senses are then classified and the theta roles are analyzed in each of the classes. The aim is to know: Is there a relation between these meaning classes and the theta roles of each class? If there is such a relation,
how is it established?
