We talk about “Noticing” language a lot in class. It means paying attention to how language is used by native speakers or near-native speakers. It’s a much better way to learn how to use a language than relying on your electric dictionary. Noticing language when you watch movies is a really good way to improve your vocabulary.
I thought about noticing again today when I saw this news story about noticing. In this case, it wasn’t language that was noticed but set design.
