Abstract
The dissertation at hand studies lexical conceptual structures and parentheticals. Lexical conceptual structures are semantic structures in which the meaning of a lexical item is decomposed into its basic components. These components are considered to conceptual constituents belonging to a number of conceptual categories. Examples of these categories are things, events, states, properties, places and paths. Parentheticals are independent syntactic structures within other structures. They comment on, add to or modify what is mentioned in a sentence. Parenthetical structures include comment clauses, non-restrictive relative clauses, complete and elliptical parenthetical clauses, nominal apposition, detached predicatives and sentential adverbs.
The thesis contrasts the source and target texts under study with respect to lexical conceptual structures and parentheticals. The source texts consist of three essays by Edward Said. The titles of the essays are ”Representations of the Intellectual”, ”Holding Nations and Traditions at Bay” and ”Speaking Truth to Power”. The English essays are translated into Arabic by Professor Mohammad Enani. The titles of the translated essays are صور تمثيل المثقف ṣuwar tamṯīl almaṯaqaf, استبعاد الأمم والتقاليد istibʿād alʾumam wattaqālīd and قول الحقيقة للسلطة qaul alḥaqīqa lissulṭa. These Arabic essays represent the target texts under study in this thesis.
The method used in the analysis of these texts is provided by lexical-functional syntax. This syntactic theory analyzes sentences by generating two types of structures. These are constituent and functional structures. Constituent structures represent the syntactic constituents of a sentence. They also clarify the syntactic category of these constituents.
