This article explores the polysemy of four negative non-verbal prefixes in Persian language (zedd ‎‎'against, opposite of', bi 'without', nā 'not' and qejr 'not, non-') based on Principled Polysemy ‎framework (Tyler and Evans 2001, 2003). First, the primary sense of each prefix is determined ‎and then it is explained how non-primary senses are derived from the primary one, hence ‎demonstrating the semantic network of each prefix as a radial category. In this research, using ‎AntConc software (Anthony, 2014), first all the occurrences of the four prefixes were extracted ‎from the Hamshahri Corpus Version 2 (AleAhmad, Amiri, Darrudi, Rahgozar & Oroumchian, ‎‎2009) and then in order to analyze research data, some of them were randomly selected. The ‎findings of the study indicate that only in three of the four prefixes under study, polysemy is ‎observed, and that the frequency of use, ease of derivation and predominance in the semantic ‎network are the best criteria for determining the primary sense. The conceptual phenomenon ‎involved in the polysemy of these prefixes is metonymy. Data analysis shows that metonymical ‎shift occurs at two levels: at the level of morpheme/prefix sense and at the level of word-‎formation, and that the former leads to more straightforward relations within the semantic ‎network. This is due to the fact that the latter requires a more complex line of imagination which ‎automatically translates into a corresponding complexity of relations in the semantic network and ‎significant reduction in the type frequency of non-primary senses as a whole.‎

The present study aimed at highlighting the possible effects of age, proficiency level, and the structural composition of Garden-Path (GP) sentences on EFL learners' comprehension. 80 Iranian EFL learners were recruited from the initial pool of 114 participants based on the results of an English proficiency test; 40 advanced, and 40 intermediate learners were selected. Moreover, two age-groups of teenagers and adults were specified based on the study's necessities. In order to determine the accuracy and also the time needed for comprehension of GP sentences, a software application was designed, which provided learners with a set of GP and non-GP sentences and depicted the elapsed time for each participant to show the correct understanding of the presented sentences on the screen. As statistical analyses revealed, the participants, apart from age and proficiency levels, had less difficulty in comprehending non-GP items. It was also concluded that different types of GP sentences imposed different degrees of difficulty for the participants to comprehend. Furthermore, "proficiency level," unlike "age," was found to be a determining factor for the comprehension of GP sentences for Iranian EFL learners.
