It follows the per sonal name, when that is used, and is generally given to members of the learned professions and to government officials who have no higher rank, such as Bey, Pasha etc. It may also indicate a definite office, as Hakim effendi, chief physician to the sultan. The possessive form effendim (my master) is used by servants and in formal intercourse.
