​Arabic Syntax: There are three parts of speech in the Arabic language: noun إسْم , verb فِعْل , or particle حَرْف the latter has  meaning only when put in a context.

 The basic difference between the three parts is the declension,  الإعْرَاب .In principle, only nouns and their adjectives have case endings to indicate their syntactic function in a sentence.
 The noun category is defined as a word with certain syntactic characteristics such as its combinability with the definite article or as a word denoting an essence.
 Unlike the definition of the noun in Western grammar, the Arabic noun category includes adjectives, pronouns and even a number of prepositions and adverbs.

 The category of the verb is defined as a word that denotes an action and could be combined with some particles.
 The particle category includes the remaining words, and their function is to assist other words in their semantic function in the sentence.
