SADi

Sadi, also spelled Saadi, is a given name and, less commonly, a surname in Persian, Arabic, and Turkish-speaking cultures. The form is a variant of Saadi, derived from the Arabic root Sa‘d meaning happiness or fortune, with the -i suffix common to nisbas or patronymics indicating belonging or relation.

The most famous bearer of the name is Saadi Shirazi (c. 1210–1291), a major Persian poet regarded as one of the greatest masters of Persian literature. His works Bustan (The Orchard) and Gulistan (The Rose Garden) blend moral instruction with social commentary and have influenced writers across the Islamic world and beyond.

In modern times, Sadi is used as a given name in various regions and among diaspora communities with Persian, Arabic, or Turkish heritage. It can also appear as a surname in some families. Variants in spelling include Saadi, Sadi, and Sadie, reflecting differences in transliteration from Arabic or Persian scripts.
