"Form of Amaryllis"
The name Amarilys is commonly a female name from the "Greek" origin.
Amarilys is a respelling of Amaryllis, the name of the flowering plant genus. The plant name was taken from Amaryllis, a shepherdess in Virgil's Eclogues, and the Spanish form Amarilis is also in use. The y in Amarilys does not change the name's source or meaning; it reflects the same pronunciation.
Amaryllis means "Fresh stream.".
The pronunciation of Amarilys is am-uh-RIL-is.
