"Variant of Rivka"
The name Rifka is commonly a female name from the "Hebrew" origin.
Rifka is a Yiddish form of the Hebrew name Rivka, the name behind the English Rebecca. Yiddish-speaking Ashkenazi Jews used it in Europe and brought it to the United States, where it appears in birth records from the 1950s onward. It is a variant of the same name in spelling and pronunciation, not a separate coinage.
Rivka means "Servant of God".
The pronunciation of Rifka is RIF-kuh.
