Language is governed by rules, or a set of explicit or understood regulations or codes. Describe each rule and give an example

What will be an ideal response?

Answer: The rules that apply to communication and interaction are phonology, semantics, syntactics, and pragmatics.
Phonology—the accepted methods for combining sound to pronounce words. For example, the letter "a" can be pronounced in different ways, such as in car, cat, and cake.

Semantics—the process of understanding the meanings of words and negotiating the complexities of language such as literal and figurative meanings, and meanings that change over time. For example, the phrase "please crack the window" typically means to open it slightly, not to break it.
Syntactics—concerns the rules for determining word order, placement, and sequencing. For example, in English, the subject usually comes first, then the verb, followed an object. Sarah opened the book.
Pragmatics—deals with how you actually language in everyday interactions. For example, pragmatics guides you in knowing what is appropriate (or not) to say in front of your grandparents.
