"Blend of Anna and Alyssa"
The name Annalyssa is commonly a female name from the "English" origin.
Annalyssa is a modern English formation built from two established given names, Anna and Alyssa. Its first appearance in United States birth records in 1990 fits the pattern of late twentieth-century American compound names. The spelling also coincides with Annalisa, an Italian compound of Anna and Lisa.
The pronunciation of Annalyssa is an-uh-LISS-uh.
