One who writes things down so they can be judged and kept — a drafting hand. A scribe proposes; the proposal awaits an eye; nothing is final by being written.
Latin scriba (a writer, clerk, public official who keeps records), from scribere (to write) — and scribere originally meant TO SCRATCH or incise, the physical act of cutting marks into a surface. From Proto-Indo-European *skribh- (to cut, separate, sift). A scribe was an office, not a hobby: the person trusted to set down what was said so it could be consulted later.
The public house for the constellation's tellings. The office sense is what is wanted — a scribe records faithfully and does not editorialise, and the cutting root is a fair reminder that writing something down makes it durable in a way speech is not.
