Starting from my story. When I lived in Melbourne, I had 5 french roommates. It was a great opportunity for me to learn French. Since then, I kept opening my ear to hear what they were saying. Of course I didn’t understand anything at first.
I realized that the pronunciation of French was a little difficult for me. Anyway, I told to myself, “It’s fine, just keep trying to mimic what they said and what their body movements are”. Then I found out there were some sentences and words showed up frequently in their chats.
For example, I observed that they would say “ça va?” and “ça va.” with each other when they woke up, and I knew it is used in greeting, like “how are you”. Also, they said “olala” when they found something interesting, so every time I found something interesting I would say olala.
What if I don’t have a target-language environment?
Don’t worry, I will provide some resources below for you to get started.
