'Alysha' is a modern English given name, derived as a variant of 'Alisha', which itself is a variant of 'Alicia', ultimately from the Old French name 'Aalis', a short form of 'Adelais', from the Germanic 'Adalheidis', where 'adal' meant 'noble' and 'heid' meant 'kind, sort, type'.

'Adalheidis' transformed into the Old French 'Aalis', which became 'Alicia' in English, and later gave rise to the modern variant 'Alysha'.

Initially, it meant 'noble kind', but over time it became used simply as a female given name without reference to its original meaning.
