"Variant of Catherine"
The name Kateri is commonly a female name from the "English" origin.
Kateri is the Mohawk form of Catherine, recorded as the name of the seventeenth-century Mohawk woman Kateri Tekakwitha. The spelling entered United States birth records in the 1930s, which is consistent with its use in Mohawk and wider Catholic communities rather than with an origin in English naming.
Catherine means "German and Swedish short form of KATHERINE".
The pronunciation of Kateri is KAT-uh-ree.
