Bright, clear, or mountain
Seaira is a modern phonetic variant of the Irish name Ciara or the Sanskrit name Saira. In its Irish roots, it relates to the word for dark or black-haired, while in other contexts it is associated with brightness or traveling. It is often chosen by parents seeking a unique spelling of the more common Sierra.
