sound. There are two necessary components that define assimilation which are a sound that changes assimilating sound and the sound that causes the change the
conditing sound while deletion rules is rule that delete phonemic segments in certain contexts.
The example of assimilation rule : in+direct :indirect
in+potent:impotent in+mature:immature
5. Theory of Word Meaning
A word, as a basic unit of the language, play important rule toward the development of any linguistic field. Rochelle Lieber defined a word as a sequence
of one or more morphemes that can stand alone in a language. Lieber.2009:12, meaning to say, a word is a fundamental element in the term of the use of
language. In the book entitled An Introduction to English Morphology Words and
Their Structure. Carstairs Carstairs, 2002:5 states: “a word is not just a building-block of sentences: it’s a building-block with
a meaning that is unpredictable or at least sufficiently unpredictable that learners of English, and even sometimes native speakers, may need to
consult a dictionary in order to discover it.” From the statement above, we can see that the word always has its own
meaning when it is used in certain sentence or any linguistic term. A word is constructed with morphemes. However, a word is not constructed only with
morphemes but also with the affix. Therefore, the meaning of a word is not only affected by the meaning of morpheme but also the meaning of affix so the
meaning will be unpredictable. Consulting the dictionary can be a way to find out
the meaning of the certain words but we just can find the meaning of a word as a single unit. There are three main types of the word’s meaning which are lexical
meaning, grammatical meaning, and also pragmatic meaning. Lexical meaning is the meaning of words which are found in the dictionary. Grammatical meaning is
the meaning related to syntactic arrangement and grammar. Pragmatic meaning is the meaning that is associated with the use of language varieties in the discourse.
C. Theoretical Framework
There are four theories used to analyze the problem in this study. Those four theories are theory of morpheme, theory of inflectional and derivational,
theory of borrowing in English Language, theory of phonology and phonetics, and theory of word meaning.
Each of the theories above has their own function in this study. The theory of morpheme is the basic theory to find out the form of the stem each complex
word in the data before the word is attached to the prefix {en-} or the suffix {-en}. The theory of borrowing in English Language can be very useful to determine the
origin of each stem. This study uses theory of phonology and phonetic to analyze deeper about the characteristics of the stem from the complex words which are
attached to the prefix {en-} or the suffix {-en}. This theory also will be very useful to know the changing of the phonological term before and after the {en-}
prefixation or {-en} suffixation. While the theory of inflection and derivation, and theory of word meaning
will have important contribution to examine the meaning of the complex words which are attached to the prefix {en-} or the suffix {-en}. Finding out the meaning
