autotype is a nineteenth-century coinage from auto- (Ancient Greek autos 'self') + type (via Latin typus from Ancient Greek typos 'impression'). Morphologically, the word is transparent as a compound: its parts remain visible in the modern spelling, while the older history of those parts supplies the deeper ancestry. In modern use, the noun sense is "a photographic carbon printing process, or a facsimile so produced", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as type, autograph, prototype and derivatives such as autotypy, autotypic, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Ancient Greek autos, Ancient Greek typos, which anchor the explanation in named linguistic material.
