The keeper of lore and the one who tells it — the memory of a place, carried in a person and given aloud. Irish, seanchaí. The keeping and the telling are one office; a record nobody speaks is not what this word means.
Irish seanchai (a keeper and teller of lore), from sean (old) + a suffix naming the one who does the telling; the keeping and the telling have always been one office in the word, not two.
