The language register used in academic communities has the special features of density, complexity, and abstractness which are associated with nominalization with which new members of the communities might not be familiar. To explore the possible distance between novice and established members regarding their awareness of this grammatical feature, the present study investigated the employment of nominalization in the writings of Iranian graduate students (both MA and PhD students) and experienced figures in applied linguistics. Forty five research articles in the discipline by the three groups of writers served as the corpus of the study. A rigorous analysis began by identifying and outlining nominalization instances manually through and per all rhetorical sections of the articles. The occurrences of the two types of nominal expressions was counted and normalized. So as to detect the possible significant differences between the samples, chi-square tests were run. The results revealed that the experienced writers used significantly more nominalization in their writings. However, although the total nominal expressions used in MA texts were more than those used in PhD texts, the difference turned out not to be significant. There were also similarities and variations in the ranking patterns of the two types of nominalization in four rhetorical sections of the three groups of the articles. It can be concluded that the differences might reflect the distance between the novice and the established authors regarding their awareness of the importance of nominalization in academic writing. The implications of the study for EAP courses were also discussed.

Advertisement has long been used as a tool for informing and attracting audiences in different ways. This study aims at investigating the linguistic tools of advertisement in Persian on the basis of Halliday’s systemic-functional grammar theory. The data of this study were gathered from written and verbal commercial advertisements which were recorded and rewritten in order to investigate verbal groups in the sentences in terms of process and function types and subsequently compare the two bodies. The results showed that material and relational processes had highest frequency in Persian language in terms of ideational metafunction. From the interpersonal metafunction perspective, information function was frequent in most cases. Regarding these factors, there was no significant difference between verbal and written bodies.
