I know all of these vocabularies, but you're kind of stuck in the middle of like - how do I become comprehensible? Then I found Sylvi" - Amira, UK "I could say, 'I'm going to the cinema today'. Then if I do Sylvi tomorrow, my penpal will come back and say, 'so what film did you see at the cinema?'. I love the continuity. It's so clever." - James, US
