@umbra21 - English is a rich language precisely because at some point someone made up a new word that precisely described a particular thing.
Shakespeare alone invented almost 2000 of our words, including things like advertising, lonely, luggage, jaded and so forth.
No language is static and I think learning to play around with words at an early age is actually quite critical for kids to develop creativity. If they don't get to read a book of nonsense or two they might never learn that it's OK to go off the beaten path and invent their own ways of doing things.
Plus it's fun. I mean, come on, just try reading Jabberwocky out loud without a smile on your face. It's very difficult to do it.
