My youngest has unintentionally, unwittingly coined a new word: "Shan"
Some weeks ago, I thought I was hearing things. "Eema, shan I finish my homework now?" "Abba, shan I give Max his supper?"
When I first asked, "What did you say, Noam?" he repeated it again. And again. And again.
It began to grow on us, even though it's absolutely wrong. I don't correct him too much on it anymore simply because I like to hear him use the word.
"Shan": another word for "should"; derived from "shall" and "can".
