Two things that continue to annoy me:
Sven the bard in Riverwood calls Faendal's note "dribble" when he clearly should have called it "drivel" (childish talk).
Sybille Stentor, Solitude's court mage, warns you that this world is "ripe" with people looking to spill your blood, when she should have said "rife" (meaning abundant, plentiful, or numerous).
I expect to see these fixed around patch 12.009821 or so.
