The Simple Future tense in Kazakh, known as "Болушылық заманы," is used to express actions or states that will occur in the future. It is formed with the future tense marker "-ау/-еу" and the verb. For instance, the verb "ойна-мау" means "will play." The suffix "-ау" is used when the last vowel of the verb root is a, ı, o, u and "-еу" is used when the last vowel of the verb root is e, i, ö, ü. Remember, each verb and subject pronoun can modify the ending of a verb in Kazakh, ensuring you match them correctly.
