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).
