The present contribution bears an attempt to take a novel synchronic perspective on derivational morphology in Persian namely canonical derivation. Introduced by Corbett (2010) and being a sub branch of canonical typology approach, canonical derivation viewpoint looks for canonical instances of single grammatical categories which are the best, the clearest and the indisputable ones rendering spectacular typological definitions. In this paper, by analyzing (195) derivational affixes including (22) prefixes and (173) suffixes, we endeavored to discover whether derivational morphology is canonical in Persian or the derivational affixes are far from canonicity in some degrees. The data analysis revealed that (%34) of derivational affixes rejected the substitutability criterion and just one suffix rejected 2 criteria. In sum, among 975 points for the fully canonical system, Persian gained 904which portrayed (%7.29) deviation from the canon; in other words, it is (%93) canonical. This amount of canonicity illustrates that derivation system in Persian is so close to the canonicity of derivation systems worldwide.

Since in modern day most of the information is conveyed through written communication, and media play a significant role in the conveyance of hot issues of the day, the language of the news has attracted the attention of both media researchers and linguists for decades. This descriptive-analytical study aimed to compare the adoption and violation of Grice‟s (1975) cooperative principles (CPs) in news reports published in Tehran Times and identify which of these four CPs (quality, quantity, manner, and relation) has been violated most and which of them has been violated least. In this regard, 120 news stories were selected randomly from the newspaper Tehran Times, in which the adoption and violation of these CPs were studied by two independent raters. Ten reports were selected from whatever published in the 12 months. Results revealed that maxim of quality was violated most, and its highest amount among five news categories was related to social news. Also, findings showed that maxim of relation was violated least, and the lowest amount among five news categories was related to cultural news, that the second highest violated maxim was the maxim of quality, and that in total maxims in the economic and social news were profoundly violated compared to the other three news categories. Findings of this study can be used by EFL learners and teachers as well as report writers in multimedia.
