gerçekletirdiniz
gerçekletirdiniz is the second-person plural past tense form of the Turkish verb "gerçekleştirmek". The verb "gerçekleştirmek" means to realize, to bring into reality, to accomplish, or to execute. Therefore, "gerçekletirdiniz" translates to "you (plural) realized," "you (plural) brought into reality," "you (plural) accomplished," or "you (plural) executed." This form is used when addressing a group of people and referring to an action or event that they have completed in the past. For example, "Bu projeyi gerçekten çok iyi gerçekletirdiniz" means "You (plural) really accomplished this project very well." The suffix "-diniz" is the past tense marker for the second-person plural in Turkish. The verb stem "gerçekletir-" indicates the causative form of "gerçekleşmek" (to become real), meaning "to cause something to become real" or "to make something happen." Thus, "gerçekletirdiniz" specifically implies that the plural subject actively caused or made something happen or be realized.
