"Variant of Ruth"
The name Ruthy is commonly a female name from the "Hebrew" origin.
Ruthy is an English familiar form of Ruth, made by adding the diminutive -y ending that English uses in pet forms such as Annie and Sally. Ruth is the name of the title figure in the biblical Book of Ruth. Reference works do not agree on the Hebrew etymology of Ruth itself, so no meaning is asserted here for either form.
Ruth means "A companion, Friendship, Loyal friend, Kind-hearted, Vision of Beauty; Compassionate.".
The pronunciation of Ruthy is ROO-thee.
