i am currently attempting to learn dutch will i eventually pick up common phrases?
Yes, some of them. However, if you just want to memorize some common phrases, then Duolingo might not be the best platform. This course is best suited for practising new words and grammar, so that you can form your own sentences.
Lucy, when you've worked your way through this course, you'll have learned a lot of vocabulary and gained a sense of the Dutch sentence structure. What's so nice about Duolingo is that there's so much help available when something confuses you. Have fun.
