Moving a bit back on topic, and going back to an earlier post from someone about using linguistics skill to influence the party, there's a great opportunity example here. The party has someone who uses a churgle, picked up from a foreigner or something. They hear of a powerful magical churgle the player then covets, and they head off to find it. Alas, "churgle" means both the weapon and something very mundane, like a serving platter or dress, or part of a building. They just don't have enough linguistics to realize that.
Maybe they figure it out before they find it Legendary Churgle, because they gain language skill. Maybe they actually find the Legendary Churgle. It's not what they thought, but there's some big win anyway. And they learn to be careful what they wish for.
