When you use words and sentences to communicate follow rules that govern how put together?

You're absolutely right! When we use words and sentences to communicate, we follow rules that govern how they're put together. These rules are called grammar.

Here's a breakdown of what grammar encompasses:

* Syntax: This governs the order of words in a sentence. For example, in English, we usually put the subject before the verb ("The dog barks" not "Barks the dog").

* Morphology: This deals with the structure of words and how they are formed. For example, adding "ing" to a verb makes it a present participle ("barking").

* Phonology: This deals with the sounds of language, including how words are pronounced.

* Semantics: This deals with the meaning of words and sentences.

* Pragmatics: This considers how language is used in different contexts.

Grammar ensures that our communication is clear, understandable, and grammatically correct.
