In Turkish grammar, Demonstrative Adjectives are commonly used to indicate or specify a noun in a sentence. These are words that identify and specify a noun, such as “this,” “that,” “these,” and “those” in English. In Turkish, the equivalents are “bu” for “this,” “şu” for “this / that / it” (mid-far demonstrative), and “o” for “that.” The usage may sound a bit complex but once you get a hold of it, it is not that hard.
