English from Greek "green shoot"; NT 1 Corinthians 1:11.
Derived by Puritans in the 17th century from a late classical Greek name, Khloë. Probably cognate with Chloris.
A correspondent [CF] notes an ancestor who was known as Clorinda [with several spelling variations], with a pet name of Chloë. This may not be common but is worth bearing in mind.
