What are the 4 types of acquisition?

There are four types of language acquisition:

1. Receptive language acquisition: This is when a child learns to understand spoken language. They may not be able to speak yet, but they can understand what is being said to them.

2. Productive language acquisition: This is when a child starts to produce spoken language. They may not be able to produce all the sounds of their language yet, but they can start to communicate using words and phrases.

3. Semantic language acquisition: This is when a child starts to learn the meaning of words and how to use them in context.

4. Pragmatic language acquisition: This is when a child starts to learn the social rules of language use. This includes learning how to take turns in conversation, how to start and end a conversation, and how to use body language and facial expressions to communicate.
