Years ago, at a bible study in our home in New York, we were looking at the text of James 4. I asked the question, “What does ‘adulterous’ mean?” (James 4:4 “You adulterous people! Don’t you know that friendship with the world is enmity with God?”)
A student from Japan heard the question and said, “Adulterous” means mature.”
An immigrant from Egypt heard that and said, “No, it means when you worship images made of stone or wood.”
So we had a good laugh (because English is an awful language to have to learn) and a spontaneous vocabulary lesson on the difference between adultery, idolatry and being an adult.
