This thesis consists of three parts and two appendices. In the course of part l affirmative, negative and interrogative sentences are discussed. Sentences of the three types are divided into different groups according to their characteristics, and various patterns of these groups are set up and analysed. After a brief introduction the discussion proceeds under three headings referring to the three grammatical categories to which these sentence-types belong, viz affirmation, negation and interrogation. At the beginning of part II the category of verbals is established and classified into groups and sub-groups, each of which is given a particular term. This is followed by separate accounts of the characteristics of two particular groups of verbs; the imperfect verb with its different forms and auxiliary verbs. } Nominals are the main theme of part III. The first chapter of this part is devoted to the establishment of the category of nominals and to the differentiation between various groups of this category. The remaining chapters -deal with important characteristics of nouns, numerals and personal, demonstrative and relative pronouns. These groups of nominals are examined as they appear in different linguistic pieces which may contain nominals only, or nominals together with forms of other categories such as verbals and particles. A: Particles and adverbs (and adverbial pieces) are classified. B: Translated texts.
