"Blend of Rosa and Isabel"
The name Rosibel is commonly a female name from the "Spanish" origin.
Rosibel is built from the Spanish name elements Rosa and Isabel, the same compound pattern seen in Maribel (Maria plus Isabel) and Anabel (Ana plus Isabel). No separate root meaning is attached to the combined form itself; the sense carried by the name sits in the two elements rather than in the whole.
The pronunciation of Rosibel is roh-see-BEL.
