The unique characteristics of Arabic, particularly the linguistic ones, made it able to keep up with the new concepts and to generate words through subjugating it to the Arabic morphology. Among these characteristics are preserving the general concepts. Each concept needs a sentence or sentences to explain it clearly. These terms are necessary for language to perform its function without repeating an expression or redundancy in sentences and structures .This is one of the reasons of simplifications in Arabic
Al-Muthanayat (Double inflected words) and Al-Muthalathat (Triple inflected Words refer to a phenomenon that has been known for the researches in linguistic fields, especially in lexicography, so what is the origin of these two terms? How have they been get their established use?
Structurally speaking, they are passive particles derived from a triliteral verb with a doubled letter. Technically speaking, this matter is related to the agreement among the scholars. If the technical terms should be formed according to the agreement of the scholars i.e. by a deliberate act, so the linguistic terms are formed in the same way but their utterances and styles are subject to the linguistic development rules. One of the many factors that affect the linguistic development is the linguistic environment since utterances have original references that develop by time. There are many terms, such as Al-Muthanayat (Double inflected words) and Al-Muthalathat (Triple inflected Words) that have come to existence without being known for their forms yet their general meaning has already been mentioned in books.
It has been decided to study one of these phenomena as it is mentioned by Al-Nasafy(died 537 A.H)- may Allah have mercy on him. This study aims at explaining the reference of jurisprudential other utterances in a study entitled Al-Muthanayat (Double inflected words) and Al-Muthalathat (Triple inflected Words) : A study of the Term and the Content.
The study consists of two sections, a preliminary and a conclusion. Section one tackles Al-Muthanayat (Double inflected words) and section two deals Al-Muthalathat (Triple inflected Words).
