Abby, having amused us with ‘Green Sheep’ has fortunately/unfortunately outgrown ‘pinecorn’ in her vocabulary. What is a pinecorn? It is a yellow fleshed fruit that is prickly on the outside that doesn’t grow on trees: a pineapple. For several months they’ve been pinecorn but finally she’s picked up that they’re pineapple and now we say good-bye to an old new word.
