Language is a symbolic, rule-governed system, shared by a group of people to express their thoughts and feelings. These rules are the set of conventions that organize their proper use and dictate how words relate to one another. Some of these rules that govern a language include phonology, syntax, morphology, semantics, etc. Morphology refers to the science of word formation. The term for a "structural part" of a word is "morpheme".It basically deals with the structure of the words and their parts such as suffix and prefix, roots and the origin of words, etc.It is defined as "the smallest meaningful element of a language, or as "the smallest unit which is grammatically significant".Morphemes can be mainly of two types: Free morphemes and Bound morphemes.Free morpheme: They can occur freely and by themselves in a word. For example, brother in brothers, teach in teacher, etc.Bound morpheme: They can not occur freely in a word but they must be bound with another morpheme. For example, -er in teacher, -ly in friendly, etc.Hence, it could be concluded that ?Morphology deals with the structure of words.
