Irys

Irys is a variant of Iris, a name derived directly from the Greek word for 'rainbow' (ἶρις, îris). In Greek mythology, Iris was the personification of the rainbow and a messenger of the gods, particularly Hera, who traveled between the heavens and earth on the arc of a rainbow. She was often depicted with golden wings and a herald's staff.

The name has been used since ancient times, though it gained more prominence as a given name in English-speaking countries in the 19th century, coinciding with a general revival of classical names. The 'y' spelling in Irys is a less common, modernized, or alternative phonetic spelling that emerged later, possibly to give the name a unique or contemporary feel while retaining its original meaning and sound.
