Leassa is English in Origin.

A rare modern English feminine given name, Leassa likely arose as a creative elaboration of Lisa/Leisa/Leesa (diminutives of Elizabeth) or as a blend with Leah plus the -ssa ending seen in Melissa and Alyssa. If taken as a Lisa-variant, its deeper root is Hebrew Elisheva, interpreted as “God is my oath” or “pledged to God.” Read through the Leah pathway, it carries the traditional Hebrew sense “weary,” though some link it to Leah’s gentleness.

Documented in late-20th-century Anglophone records, Leassa has remained rare, with sporadic use in the United States, Canada, Australia, and the UK, aligning with an era of customized spellings. Related forms include Leasa, Leesa, Leisa, Leissa, Liesa, and the base names Leah and Lisa; short forms Lee and Lea are common. Its fluid spelling keeps meaning and origin flexible, allowing families to link it either to Elizabeth’s devotion or Leah’s understated strength.
