Alysah is of Hebrew origin and signifies 'wisdom'. It is a variant spelling of Alice, which has been popular for centuries. The name Alysah gained prominence in the late 20th century and early 21st century, often used as an alternative to more traditional names like Alice or Alyssa.
"The name Alysah saw its most popularity between 1999 and 2007, with over 14 births each year during this period. However, it seems the name's usage has declined since then, with fewer than 10 births per year from 2008 onwards, except for a brief spike in 2013."
