Phonology has to do with organized sounds used in natural languages. It is a variety of sounds and the features of those sounds. Phonology constitutes specific rules of the interaction of sounds with each other.

Phonology relates to other aspects of language such as morphology and phonetics. It determines the kind of phonetic sound and their significance as well as the explanation and interpretation of sounds by the native linguist. It is similar to the way in which language constitutes syntax and vocabulary.

Phonology is a descriptive preface to the way that sounds function in any language. Sounds are combined in their specific unit of a language. An example of this in the English language is the sound that “p,” makes in the word, “pet,” includes the aspirated feature.

However, in the word, “group,” the “p,” becomes the final ending of the word and does not have an aspirated feature. In other words, even though, it is the same letter, “p,” the sounds when incorporated in each word is different.

It is easy to observe that different languages have different combination of sounds for any given word. Certain sounds are found in specific languages while absent in the next. In a specific language, sounds are different because of vowel interchanging that form those words.

The goal of phonology attempts to be accountable for the similar ways in which sound affects different languages. It also seeks to describe the rules of sound and its structure within a specific language.

Although, different languages have different combined sounds and a variety of ways to arrange and pattern these sounds, it goes without saying that there a few similar ways in which they span the human language on a whole.
Some of these similar ways that are universal to all languages are:
1.    Every consonant has a voiceless stop
2.    Every language has syllables
3.    Every inventory can be divided into vowels and consonants.

Conclusion

Correction pronunciation is important in any language and phonology makes sure that this becomes a rule. There are some linguists who incorporate phonetics within the scope of phonology to make it easier for the person learning a second language.
