In Azerbaijani grammar, the definite article does not exist as a separate word, but instead is shown through the use of the suffix “-ı, -i, -u, -ü”. This suffix is added to the end of a noun to indicate that it is definite, meaning that it refers to a specific object or person. The choice of “-ı, -i, -u, -ü” depends on the vowel harmony rules of Azerbaijani language. In this exercise, you will practice using the definite article suffix in Azerbaijani sentences.
