This document is the first part of Lesson 1 from an Arabic language course. It introduces the demonstrative pronoun "hādhā" which means "this" in Arabic. Some example sentences are given to demonstrate how "hādhā" is used followed by the noun, without an equivalent of the verb "to be". The lesson explains there is no word for "a" or "an" in Arabic, and the nunation (tanwin) on nouns serves this purpose. It encourages the reader to proceed to Part 2 to practice further.
