I highly recommend
- L-Lingo to study Vietnamese vocabulary and here is the link to their website . It was made the way I think vocabulary lessons should be made. The lessons are basic though.
- everydayviet.com also have some fun, easy to follow basic phrases. They also have a YouTube channel under the same name.
Occasionally I will add some lessons of my own (for fun!), but since my vocabulary lessons are a lot more intensive, it takes time for me to write and you to digest🙂
