Bengisu
Bengisu is a Turkish-origin name with poetic meaning and contains no elements that conflict with Islamic naming principles; it is commonly used by Muslim families in Turkish-speaking regions.
The name combines Old Turkic 'bengü' (eternal) with Turkish 'su' (water); both elements are well-documented in Turkic linguistic history.
No, Bengisu is relatively rare compared with mainstream Turkish names but is recognized and occasionally used, prized for its poetic connotations.
There are no widely attested masculine equivalents used historically; the compound structure '...su' is primarily seen in feminine Turkish names.
Pronounce it as BEN-gee-soo; in Turkish the 'g' is pronounced as a softened /ɟ/ and the stress commonly falls on the second syllable.
