نگرش دستور شناختی به پدیدۀ حذف در ساخت‌های همپایۀ فارسی

در این پژوهش، به بررسی چگونگی مفهوم‌سازی حذف در ساخت‌های هم‌پایه فارسی، با رویکرد دستور شناختی پرداخته‌ایم. از دید لنگکر (langacker, 2012, p. 585)، حذف به مواردی گفته می‌شود که در آن‌ها یک عبارت، جمله نیست، ولی در قیاس با عبارت دیگری که جمله است، تفسیری جمله‌گونه می‌یابد. بر مبنای پژوهش‌های انجام‌گرفته در زبان انگلیسی، انتظار بر آن بود که دستور شناختی با کمک مفاهیم متمایز و ضد متمایز از عهدۀ تبیین حذف در ساخت‌های هم‌پایه فارسی برآید. برای آزمودن این امر، تعداد 405 دادۀ دارای ساخت همپایه از دو روزنامۀ پرشمارگانِ شرق و اعتماد گرد‌آوری شده و ساخت‌های دارای حذف را از متن آن‌ها برگزیدیم. سپس، با کمک ابزار نظری پژوهش، به بررسی آن‌ها پرداختیم. یافته‌ها نشان دادند که حذف ساخت‌های همپایه در زبان فارسی به کمک پنجره‌های توجه و بر اساس مفاهیم متمایز و ضد متمایز قابل‌تبیین است، به گونه‌ای که متمایز و ضدمتمایز، همپایه‌های ساخت موردنظر را تشکیل می‌دهند. بنابراین، بدون در نظر گرفتن کلاسیک بودن یا نبودن سازه‌های همپایه‌، حذف ساخت‌های همپایه در زبان فارسی بدون ایجاد چالش برای نظریه در چارچوب دستور شناختی تبیین می‌شود.

the viewpoint of cognitive grammar to ellipsis in persian coordinative constructions

this study aims at the investigation of ellipsis in persian coordinative constructions. langacker (2012) speaks of ellipsis in cases where an expression that is not a clause itself, receives a clause-like interpretation by analogy to one that is. most of the research on ellipsis in coordination regarding persian have adopted a generative grammar approach. generative linguists seemingly do not hold a unified opinion about ellipsis coordination or what they call  right node raising. shabani (2013) has mentioned that constituency or non-constituency of the omitted part is a subject of controversy among different generative linguists. on the one hand, linguists, such as postal (1974), bresnan (1974), williams (1990), and larson (1990) claim that right node raising only works on the elements forming a constituent. on the other hand other linguists, including abbott (1976), wilder (1995), duman (2003), kluck (2007), wyngaerd (2007), ince (2009), and  alzaidi (2010) argue that right node raising targets non-constituents as well as constituents, and this means that right node raising violates constituency condition.  having this in mind, it seems that the fixed and rigid constituency defined by generative grammar has caused some challenges for this kind of constructions description. hence, adopting cognitive grammar approach, which is meaning-based instead of syntax-oriented and investigates language with all aspects of it, has rendered new and different results.langacker (2009) argues that meaning includes not only conceptual content but also construal: our ability to conceive and portray the same situation in alternate ways. in order to have a uniform way of referring to (conceptual) content, the term domain (base) is adopted in cognitive grammar. one dimension of construal is the prominence conferred on conceptual elements, and one kind of prominence – profiling- is of central importance in coordination. this is how meaning plays a significant role in our analyses. langacker (2012) introduces differential and anti-differential as the coordinands of an elliptic coordinative construction. he defines differential and anti-differential in the framework of a model named as access and activation model. based on this model, on a given time scale processing takes place in successive windows. a window provides the extensionality required for multiple entities to be represented and connected with one another. canonically, the content subsumed in a window is thereby integrated to form a coherent structure organized around a single focus, or salient entity (langacker, 2012). in the same work, langacker refers to the windows coinciding with clauses as clause-sized windows. langacker (2012) employs access and activation model as an alternative metaphor for compositionality.  as he  puts it, the linguistic notion of composition is based on the metaphor of building something out of smaller pieces. while it is unavoidable, useful, and valid up to a point, the compositional metaphor has its limitations and is deleterious if pushed too far. in this alternative metaphorical model, a moving window of attention provides serial access to a complex conception. portions of this target conception appear in the window at each processing stage until it is deemed to have been covered sufficiently for communicative purposes. differential is defined as the content appearing in one clausal window that does not appear in the prior window. the anti-differential consists of any previously active content that the differential conflicts with and suppresses (langacker, 2012). based on langacker’s research carried out on english, it was expected for cognitive grammar to manage to describe ellipsis in persian, considering differential and anti-differential as the coordinands of the coordinative constructions.
