Aronoff and Fudeman (2011: 2) states that morphology In linguistics, “refers to the mental system involved in word formation or to the branch of linguistics that deals with words, their internal structure, and how they are formed”
There are various ways to define a word, but no definition is entirely satisfactory and Scholars around the world have acknowledged this fact over and over again. Delahunty and Garvey (2010) point out that in traditional grammar, words are the basic units of analysis. Hence grammarians classify words according to their parts of speech and identify and list the forms that words can show up in. Although the matter is really very complex, for the sake of simplicity it will begin with the assumption that we are all generally able to distinguish words from other linguistic units. It will be sufficient for our initial purposes if we assume that words are the main units used for entries in dictionaries.
McCarthy (2002) states that, “words are the basic units of language”. Some observations about words and their structure:
1. Some words can be divided into parts which still have meaning
2. Many words have meaning by themselves. But some words have meaning only when used with other words.
3. Some of the parts into which words can be divided can stand alone as words. But others cannot
4. These word-parts that can occur only in combination must be combined in the correct way
5. Languages create new words systematically
