"Novo dicionário da língua portuguesa" by Cândido de Figueiredo is a Portuguese language dictionary published in 1899. First released by Livraria Editôra Tavares Cardoso & Irmão, this comprehensive reference work underwent twenty-five editions across nearly a century, passing through multiple publishers in Portugal. After the author's death in 1925, the 1913 edition entered the public domain and was digitized by volunteers, becoming freely available online and spawning web-based adaptations that continue to serve Portuguese speakers worldwide.
