* Αὐτογράφος (autographos): This literally means "self-written," but it typically refers to an autograph (a signature or inscription written by hand). It's not ideal if you're thinking of a broader sense of self-authored content.
* Αὐτο- + some verb root related to writing: You could combine the prefix `αὐτο-` (auto-, meaning self-) with a verb root related to writing. For example:
* Αὐτοσύντακτος (autosynstaktos): This combines `αὐτο-` with `σύνταξις` (syntaxis, arrangement, composition). It would mean something like "self-composed" or "self-constructed," which could work depending on the context. However, it emphasizes structure rather than the act of writing itself.
* Αὐτογράφητος (autographetos): Combining "auto" with a past participle of a verb related to writing. Less common and slightly more awkward.
The best approach depends heavily on context. If you can provide more context about how "self-write" is being used, I can suggest a more precise and natural-sounding Greek equivalent.
