Etymology of formidable
According to Projet-voltaire.fr, until the beginning of the 19th century, the only usage of formidable was to describe a person, object or situation which caused fear. In Latin, the adjective formidabilis translates to “causing or inspiring fear”. It’s only in modern French that the meaning of formidable has taken on a postive connotation to mean “great” and “terrific”.
