Morphology examines and studies how words are structured internally. It also looks at the way words are formed and the rules that go along with them.

Morphology spans three primary approaches that embrace the difference of each model in different ways. These three approaches are:

1.    The item and arrangement approach - Morpheme
2.    The item and process approach - Lexeme
3.    The word and paradigm approach – Word-based

These are strongly associated, but do have their differences and are not unlimited in how they are applied to the new language. According to the morphology model, a student will have knowledge of a word when they become familiar with:

1.    The spelling of the word
2.    The pronunciation of the word
3.    The definition of the word
4.    The part of speech of the word
5.    The history of the word
6.    If the word is improper
7.    If the word out of date
8.    Examples of the word
9.    Any slang associated with the word
10.    The root and stem of the word

With morphology, students who can analyze and identify a word in a second language; would have mastered the language to some degree. Rules in most languages determine how closely related words are.

For example in the English language, native speakers may be able to relate to the words, cats, cat, and cat food. They intuitively make inference to the fact that cat is to cats as bird is to birds. In a similar instance, cat is to cat food as bird is to bird feed.

The way that a student identifies both words; cat and cats as being related or similar is known as lexeme. On the other hand, bird and bird cage are different lexemes because they fall into different categories of word form.

The student understands the rules in terms of precise patterns in which the word is formed in a sentence or phrase.

Conclusion

So it is conclusive to say that morphology is an area of linguistics that is the study of the pattern in which words are formed within any language. It tries to form rules that are a representation of the knowledge of the students that speak the languages.
