What Ernesto means
Ernesto means serious, or vigorous in combat. The Germanic word carried the seriousness of a real fight before English softened it toward sincerity, long before English softened it toward sincerity.
Where Ernesto comes from
Ernesto is the Italian and Spanish form of Ernest, from the Germanic ernust — seriousness, and specifically the vigor of battle. The English phrase in earnest preserves the older force: to fight in earnest is to fight for real. Earnest and Ernestine, elsewhere on this site, descend from the same word, and Wilde's play turns entirely on the pun between the name and the adjective.
