find a partner to practice with.

I still make grammatical mistakes that I shouldn't be making. I sometimes still struggle to find the right words to express myself because I have a somewhat small vocabulary bank compared to native speakers. Even though I have lived in the U.S. for over 15 years and I speak English every day, I still feel like my English is not where it should be :/

Know a lot of grammatical rules and vocabulary, but cannot communicate fluently with native speakers.

suitable phrasal verb

During the conversation, a vocabulary stuck in my mind, I try to explain with a sentence but it ends up with a too long sentence then I forget the key message that I would like to say... haha
