Abstract :
The research discussed about derivational morphemes of suffix -er, -or,
ist, ian, and -ant as Agent. The reason why I choose derivational morphemes of
suffix er, -or, -ist, ian, and -ant as Agent as my basic analysis source is because
I find that many beginning students whose vernacular language is not English are
confused of determining the agent based on definite suffix. The basic problem of
my assumption is that the suffixes of -er, -or, -ist, ian, and -ant as Agent are
attached depend the last word sounds. Trying to prove my assumption, I
conducted the research through morphology and phonology approach. I employ
some theories and ideas from the linguists concerning on morpheme, roots,
affixes, bases, derivation, sound classes, vowels, consonants, parts of speech, and
the last word sounds.
In this research, I systemized my analysis by using parts of speech and the
last word sounds. In analyzing bases through parts of speech, there are three kinds
parts of speech that are attached in suffixes of -er, -or, -ist, ian, and --ant as
Agent, namely verbs, nouns, adjectives. In analyzing bases through the last word
sounds, there are can be identified based on vowels (diphthongs, monophthongs)
and consonants.
Finally, in the last chapter, I conducted that derivational morphemes of
suffix -er, -or, -ist, ian, and -ant as Agent are attached depend on the last word
sounds.
