Ask a name and respond warmly
你叫咩名呀？ asks someone's name. The answer may contain a name unfamiliar to you, so listen for the words around it as well as the name itself.
好開心識到你 says you are glad to meet the person. Hear both lines as parts of a short exchange rather than as unrelated vocabulary.
Keep the exchange going
For someone you already know, 你最近點呀 asks how they have been lately. 冇咩特別 is one possible casual answer. These lines belong to a different moment from a first introduction.
You can also make a simple plan with a friend. 一齊去吖 suggests going together. That gives you a natural next sentence after the greeting.
Talk about the people close to you
我屋企人 means “my family.” When making plans, you can also ask whether someone has arrived or say that you are nearly there. Each expression becomes more useful when you attach it to a real person and place.
Try a tiny conversation: ask a name, greet the person, and later check whether they have arrived. Hear the whole line before repeating it.
