Ta'lîl (causality) letters in the Arabic language

Words in Arabic consist of nouns, verbs and letters. While the nouns and the verbs have a meaning, the letters by themselves are meaningless and are directly responsible for the construction of the sentence. There are many factors that provide meaning to the sentences formed by the words joining together. One of the factors is the cause-and-effect relationship. The major aim of this research, which is called "Ta'lîl (Causality) Letters in the Arabic Language", is to review in detail and to present Ta'lîl letters establishing a cause and effect relationship and the meanings created by these letters. This study consists of an introduction and two different chapters. The introduction part briefly discusses the Ta'lîl word and its usage differences and details the subject, scope, aim, objectives and method of the study. In the first chapter, the lexical definition, word meaning and synonyms of the Ta'lîl words is elaborately investigated and all related literature is reviewed and given in the chapter. Furthermore, this part of the investigation paper is contributed to the identification of the 'Causality' word, which is a commonly used form of Ta'lîl statümsen. There, the differences between these words, their usage patterns preferred by grammarians and the subject of word types in Arabic under a conceptual framework are also included. On the other hand, in the second section of the study, the thirteen words defined as Ta'lîl letters are considered under separate headings. Besides, to make it more understandable, the usage figures of these words with the purpose of providing a cause-and-effect relationship tor the sentences are supported by the examples from the Qur'an, poems, and daily speeches. In the conclusion, the crucial information about the subject of Ta'lîl is highlighted and summarised.
