Ahmed Effendi, better known by his mahlas (nom de plume) Nedîm (Ottoman Turkish: نديم; c. 1681–1730), was an Ottoman lyric poet of the Tulip Period. He achieved his greatest fame during the reign of Ahmed III. He was known for his slightly decadent, even licentious poetry often couched in the most staid of classical formats, but also for bringing the folk poetic forms of türkü and şarkı into the court.
Not much is known about Nedîm's early life, except for what can be inferred from records of the time. Nedîm (then Ahmed) was born in Constantinople, most likely in 1681. His pre-nomial Mülakkabzâde (lit. descendant of the nicknamed [man]) was given to him as a result of his grandfather Merzifonlu Mülakkab Mustafa Muslihiddin Efendi; a kazasker who was known as a "man of unusual preferences", and was nicknamed as such, before being lynched in front of the Sultan Ahmed Mosque in 1648.
As the son of Kadı Mehmed Effendi, and a family vested in Ottoman bureaucracy, Nedîm's education is thought to be quite robust, including a variety of sciences, as well as "enough Arabic and Persian to write poetry." Following this education, he passed an examination process led by Shaykh-al Islam Ebezâde Abdullah Effendi, and started work as a scholar in a madrasa. While the exact date of this examination is unknown, it is known that Nedîm had already started to publish poetry by this time. Despite this, he continued to work as a teacher and scholar, in schools such as the Molla Kırîmî, Nişancı Pasha-yı Atîk, and Sekban Ali Pasha madrasas, eventually becoming a leading scholar in the Sahn-ı Seman Madrasas while teaching various subjects until his death in 1730.
While his first poems were most probably published before this, Nedîm's more traditional qasidas had become quite well known by the start of Ahmed III's reign in 1703; these had helped him obtain connections with high-ranking officials, such as Nevşehirli Damat Ibrahim Pasha, who would later offer him patronage, as he considered Nedîm's odes to be superior to other poetry written to his name.
