Īrisa

The name Īrisa is a variant of Iris, which comes 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. She was said to travel on the rainbow to deliver messages between the heavens and Earth. The flower iris is also named after her due to its wide variety of colors.

The name has been used in various forms across different cultures, often retaining its association with beauty and color. While 'Iris' is more common in English-speaking countries, 'Īrisa' might be found in regions where a slightly different transliteration or pronunciation of the Greek root is preferred, or as a modern variant.
