E = English, V = Vietnamese, P = Pronunciation
Unfortunately in Vietnamese, it isn't as simple as 'you' and 'me' or 'he' and 'she'. There are different ways to address someone, depending on their age, gender and your relation to them. Learning and understanding when to use these will probably be the hardest of the lessons.
A lot of these titles literally refer to someone as if they are related to you, so just think of everyone as your family and hopefully, you'll understand the titles better.
