How do you say come in cantonese?

There are a few ways to say "come in" in Cantonese, depending on the context:

Formal:

* 入嚟 (jap lai): This is the most common and formal way to say "come in." It literally means "enter inside."

Informal:

* 入 (jap): A shorter and more informal version of "入嚟."

* 入去 (jap heoi): Similar to "入嚟," but with a slightly different tone.

* 进来 (jin loi): This is more of a Mandarin phrase but is sometimes used in Cantonese as well.

For specific situations:

* 请进来 (cing jap lai): "Please come in."

* 入嚟坐 (jap lai zo): "Come in and sit down."

The best choice will depend on the situation and your relationship with the person you are speaking to.
