Today’s One Big Happy:
Ruthie confuses decaffeinated and decapitated, which I would have thought was an unlikely glitch, since both are relatively rare words (though phonologically very similar) — but maybe with decapitations in the news recently, the second word was more salient for her (how much current news do 6-year-olds get?).
And then she creates a portmanteau, decapinated, of the two words.
