What does the name Kaira mean?
Kaira is a spelling of Keira, pronounced the same way, so it shares Keira's meaning and origin.
Keira is a modern English spelling of a feminine form of Kieran. Kieran anglicizes Irish Ciarán, which Wiktionary explains as a byname from ciar, black or dark, plus the diminutive -án: "little dark one." Wiktionary notes that Irish saints from the 5th century on made Ciarán popular. Keira, a modern formation, carries the same "dark" meaning over to a girl's name, and spellings such as Kiera and Ciara are close relatives.
