语言中的词语（ألفاظ）用来表示意义。单一的词语（لفظ）可以只指示一个意义，例如“Baghdaad”（巴格达）表示以此名著称的那座城市。一个词语也可以指示多个意义，例如“Ain”（眼睛）既可指水的“Ain”（泉眼），也可指能看见的“Ain”（眼睛），还可指间谍等其他意义。词语还可以指示两种或更多的意义，例如“Ar-Rijaal”（男人们）：它指示所有具备“Ar-Rajul”（男人）这一描述的人，同时也可指示在其类别（جنس）中普遍存在的所指意义（مدلول），例如：“Rajul”（一个男人）。

Alfaazh (wordings) have been provided within the language to indicate meanings. The single Lafzh can indicate one single meaning like: ‘Baghdaad’ is indicative of the meaning of the city that is known by its name. A Lafzh can also indicate many meanings like: ‘Ain’ (eye) which is indicative of the meaning of the ‘Ain of water (spring), the ‘Ain that sees (eye) and the spy amongst other meanings. The Lafzh can also be indicative of two meanings or more like the Lafzh ‘Ar-Rijaal’ (men) as it is indicative of everyone within whom the description of ‘Ar-Rajul’ (man) is realised and it could also indicate to an indicated meaning (Madlool) that is widespread within its type (Jins) like: ‘Rajul’ (A man).

基于词语（Alfaazh，即措辞表达）的这种设定方式，词语根据其涵盖范围的广狭，被划分为若干类别，即：Al-‘Aamm（通用词）、Al-Khaass（专用词）、Al-Mushtarak（共用词）、Al-Mutlaq（绝对词）和Al-Muqayyad（限定词）。

Based upon this way that the Alfaazh (worded expressions) have been provided and set, the Alfaazh have been divided in respect to their comprehensiveness or lack of comprehensiveness into a number of categories which are: Al-‘Aamm, Al-Khaass, Al-Mushtarak, Al-Mutlaq and Al-Muqayyad.
