ROSA (1)   female   Spanish, Italian, Portuguese, Swedish, Norwegian, Danish, Dutch, German, English
Generally this can be considered a Latin form of ROSE, though originally it may have come from the Germanic name ROZA (2). This was the name of a 13th-century saint from Viterbo in Italy. In the English-speaking world it was first used in the 19th century. A famous bearer was civil rights activist Rosa Parks (1913-2005).
ROSE   female   English, French
Originally a Norman form of a Germanic name, which was composed of the elements hrod "fame" and heid "kind, sort, type". The Normans introduced it to England in the forms Roese and Rohese. From an early date it was associated with the word for the fragrant flower rose (derived from Latin rosa). When the name was revived in the 19th century, it was probably with the flower in mind.
ROZA (2)   female   Ancient Germanic
Old Germanic short form of feminine names beginning with the element hrod meaning "fame".
