"Variant of Alcides"
The name Alcide is commonly a male name from the "Greek" origin.
Alcide is a given name attested in French and Italian use, borne by the French naturalist Alcide d'Orbigny (1802-1857) and the Italian statesman Alcide De Gasperi (1881-1954). It corresponds to the classical Latin Alcides, from Greek Alkeides, a byname of Heracles formed from the name of Alcaeus, his grandfather, so the literal sense is descendant of Alcaeus. The form without the final s is the French and Italian rendering of that classical name.
Alcides means "Descended from Alcaeus".
The pronunciation of Alcide is AL-side.
