Genesis is the Greek word for “origin” or “beginning.”
From Greek 'iris' meaning 'rainbow'; Iris was the Greek goddess of the rainbow. The iris flower was named for its rainbow range of colours, so the name functions both as a bloom word and a word for 'rainbow'.
Iris is more popular than Genesis today: about 3,729 US babies were given the name Iris in 2025, compared with 3,527 named Genesis.
Genesis means Origin, beginning (Greek origin), while Iris means Iris flower / rainbow (greek origin).
In US records, Genesis first appears in 1964 and Iris in 1880, so Iris has the longer recorded history.
