Grunger (Grungeress?), I enjoyed your Betty Batty discourse - thanks for that!
Jigjag, I have to say that I have never used - when speaking of anything contemporary - 'governess' or 'schoolmistress' (or 'schoolmaster' for that matter. I think some words evolve, some words die out -and the impact on people varies tremendously. As the recent PU stuff shows, some losses are heart-felt by some, welcomed by others. The batty batter falls into another category altogether - nonsense for the sake of nonsense!
