Some people say that dialects and languages can be considered as codes. A language is known to be a written and spoken form that can be uniform throughout a certain place. This explains why there are a lot of countries that come with their own language although there are some that may know more than one language. A dialect is also some sort of code but instead of being used throughout the whole country, it can be used for a smaller location.
For example, it can be the code that will be spoken and written by those who live in a particular location. Those from outside that location will not be familiar with the dialect anymore.
You often use dialect and language in place of each other, it is good to be enlightened about their differences to avoid mistakes. A language is a form of communication that involves using words or signs used by a particular country or community. Language is often related to the history and culture of the place it is spoken.
A dialect is a variety of language that is spoken by a particular area, community or group and usually with differences in pronunciations, spelling, vocabulary, and style.
There mainly two types of dialects which are linguistic dialects which involve the speaker from another language understanding the speakers from other forms without learning it and sociopolitical dialects which are languages that are considered less important because of social or political reason.
