autógrafo
/auˈtoɡɾafo/ · B2 · adj
handwritten
✍️ auto (self) + grafo (written) = written by one's own hand
From Greek autós, self, plus gráphō, to write. An autógrafo is something the author wrote personally. Same roots appear in auto-matic and foto-grafía, so the pattern self + write is easy to reuse.
