Shadi Shahnaseri دانشگاه اصفهان author text article 2009 per Following on from Chawla (1991) who seeks the root of all environmental crisis in language, the present paper first introduces ecolinguistics as a new area in recent linguistic studies, and then examines the inadequacies of the language of science in reflecting ecological events and phenomena att the two level of lexis and grammar. For this purpose, a corpus was established containing sample articles in Persian journals concerning ecological issues, and later examined in terms of ecolinguistics. The qualitative and quantitative analyses revealed high frequency of scientific terms and euphemisems at the lexical level and of the passive and conditional structures at the grammatical level. The results also showed that personal pronouns and tense were covertly present in the scientific discourse of the corpus.   Linguistics Society of Iran 23223847 5 v. 10 no. 2009 1 26 http://lsi-linguistics.ihcs.ac.ir/article_1554_2e06b931eb83e884af57526b17057a4f.pdf Gholamhosein Karimi Doostan دانشگاه تهران author Arman Zaker دانشجوی دکتری دانشگاه علامه طباطبایی author text article 2009 per Persian dictionaries and grammar books do not agree on the parts of speech of a considerable number of lexical words including infinitives, predicative nouns and adjectives and light verbs of the language and this may cause problems for the learners and the researchers of this language. In the modular grammar approach, language is divided into independent modules which may not correspond in some lexical entries. Based on a study in which words were chosen from Persian dictionaries, books and journals which considered mismatching words, the present paper argues that it is possible to account for the mismatching behaviors of the above groups of Persian words in the framework of modular grammar and terminate the disagreements on the parts of speech of these words.  Linguistics Society of Iran 23223847 5 v. 10 no. 2009 27 46 http://lsi-linguistics.ihcs.ac.ir/article_1555_16cbcaed62908cff4fcb8d31aa8fee77.pdf Shahla Sharifi دانشگاه فردوسی مشهد author Sanaz Alipour دانشجوی دکتری زبانشناسی دانشگاه فردوسی مشهد author text article 2009 per After surveying the theoretical foundation of Grice,s co-operative principle on the base of meaning and intention in this research, it is tried to analyze two conversational texts(one Persian and one English Play)by adopting analytic- descriptive method and resorting to the maxims that Grice had proposed for exchanging efficient information among participants in a language interaction. First we will refer to the ways we can use not to observe the maxims. Then we draw some tables which are included the distribution of non- observance of Gricean Maxims in both plays. We also refer to ways and intentions which may cause breaking those maxims. At the end we examine differences between non- observance of maxims in these two texts and give some explanations for possible reasons of these differences. The result of this research can be used for teaching the Persian and English languages, as a second language, as well as for translating Persian into English and vice versa  Linguistics Society of Iran 23223847 5 v. 10 no. 2009 47 68 http://lsi-linguistics.ihcs.ac.ir/article_1556_e7d0f7263a8b0a7ad9ea58b304672c85.pdf Arsalan Golfam دانشگاه تربیت مدرس author Mostafa Assi پژوهشگاه علوم انسانی و مطالعات فرهنگی author Ferdows Agha Golzadeh دانشگاه تربیت مدرس author Fatemeh Yousefi Rad دانشگاه پیام نور author text article 2009 per This paper, argues that the common practice used in traditional Persian grammar books concerning prepositions, and in this special case the preposition /az/, of presenting a long list of meanings with no mention of the relationship among different meanings of each preposition is not adequate. The more adequate way, introduced in this paper, is presenting a family resemblance semantic network, based on a prototype. This method shows the conceptual relations among the senses and therefore refutes the common assumption that the meanings of prepositions are quite arbitrary.

The relevant linguistic variables were extracted from the speech of 24 qualified (adolescent, young and adult) informants. The findings of this study show that education, in the case of some linguistic variables, does not cause a decline in the use of non-standard forms and it just plays a significant role in differentiating the speech of literate and no-literate adults. It is also observed that, in employing some of linguistic variables, the men’s speech is more standard than women’s. Furthermore, in cases where the speech of women being more standard than that of men, their speech differences are trifling and the role of age is not distinctive. The increase in the age of the adolescents having literate parents and literate adults correlates with the increase in the use of standard linguistic forms. In adolescent groups, in half of the linguistic variables studied, the gender does not make a distinction between the speech of boys and that of girls.

As our most prominent classic literature figure dynamic, great imagination, he creates the most beautiful, mystical imaginations in the wide range of unique arrangement of words and diversified poetic depictions. Thus, the works of this famous figure can be scientifically reviewed as a considerable discussion of different linguistic approaches and literary critic. Therefore, with the purpose of reviewing effectiveness of collocations as a well-known linguistic subject in today’s linguistics, we intend to review the effectiveness of this subject in the literature and description and clarification of different types of it in the selected works of Molana including “The six Books of Masnawi”, “Fih ma Fih” in this article.

This research seeks to investigate the lexicon in machine translation (MT) systems, and then to propose a representation system for its lexicon using concepts and relation links between them, which can be utilized to enhance the efficiency of MT systems. Finally, the performance of this mechanism is illustrated through conceptual graphs.

The Parthian one is about an incident in one of Mani's travels. This text, which has been categorized as an historical text somehow coincides with the first text and, apparently, the same characters are involved in both of them. In fact, these two texts complete each other. In this article, along with a linguistic study of the texts, the cultural roots of the "sin of wailing" in the Manichaean religion are examined.
