Meaning and history
Allissa is a modern English feminine spelling variant of Alyssa or Alissa. Alyssa was influenced by the name of the alyssum flower, whose botanical name comes from Greek elements associated with curing madness; Alissa may also relate to Alice, from the Germanic name Adelaide, “noble kind.” Because the spelling can reflect either route, one fixed ancient meaning is inappropriate. Reliable prominent bearers using the exact spelling Allissa are uncommon.
In 2018, 10 babies were recorded with the name Allissa, ranking #9,806 among girls.
