Syleena / Selene / Celina

Syleena is a modern English name, likely a variant or elaboration of Selena or Selina. The name Selena itself derives from the Greek word 'selēnē' (σελήνη), meaning 'moon'. In Greek mythology, Selene was the Titan goddess of the moon, often depicted riding her moon chariot across the night sky.

The 'y' in Syleena might be an aesthetic alteration, common in modern name creation, to give it a unique spelling or sound. While Selena has ancient roots, Syleena is a more recent coinage, gaining some usage in the late 20th and early 21st centuries, particularly in English-speaking countries.
