IPA: /ɔːˈtɒɡrəfi/
KK: /ɔːˈtɒɡrəfi/
A collection of autographs or signatures from various people, often valued for their historical or personal significance.
The museum displayed an impressive autography of famous authors and musicians.
Autography is formed from "auto-" (meaning self) and "graphia" (from Greek "grapho", meaning to write). The word refers to writing done by oneself, particularly one's own signature or handwriting.
Think of 'self' ('auto-') writing ('graphia') — that's why autography means writing by oneself.
