1. Not listening enough
There’s a school of linguistics that believes language learning begins with a "silent period”。 Just as babies learn to produce language by hearing and parroting sounds， language learners need to practise listening in order to learn. This can reinforce learned vocabulary and structures， and help learners see patterns in language.
Listening is the communicative skill we use most in daily life， yet it can be difficult to practise unless you live in a foreign country or attend immersive language classes. The solution? Find music， podcasts， TV shows and movies in the target language， and listen， listen， listen， as often as possible.
