For questions about the basic move "Spout Lore" in Dungeon World, used for recalling useful knowledge.

Spout Lore is a basic move in Dungeon World, which permits a character to try recalling useful knowledge, as long as it might be possible that they've learned what they're talking about somewhere; it can provide either useful information, interesting (but not useful) information, or an opportunity for a GM move on a 6-.

Basic rules for the move can be found in the Moves chapter, hosted here on Github; this topic is for concerns about the adjudication and limits of the move in play.
