Based on the article from Krashen, it would be helpful in comparing Tonya with this study because this study would emphasize the second language
acquisition of Tonya in acquiring English vocabulary because Tonya is already six years old. It means that Tonya already gets the second language acquisition
from her environments. Unfortunately, in other hand, this article is difficult to be understood because there is no example in each explanation. E, g; in the formal
and informal linguistic environments, Khrasen does not give the example of formal linguistic environments and the informal linguistic environments.
2.2 Concepts
The concepts of this study are based on the applied linguistics. The concept, which would be presented here, are:
2.2.1 The concepts of Language
According to Chomsky 1968:47, knowing a language means being able to produce an infinite number of sentences never spoken before and to
understand sentences never heard before. Chomsky refers to this ability as the ‘creative aspect” of language.
According to Rice-Johnston 2008, language is the process or set of processes used to ensure there is the agreement between the sender and receiver
for meanings assigned to the symbols and the schema for combining them used for each communication.
According to Sapir 1921, language is the material or medium of literature. Literature may move on the generalized linguistic plane or may be
inseparable from specific linguistics conditions. Language is a collective art.
Style as conditioned by inherent features of the language. Prosody as conditioned by the phonetic dynamics of a language.
Based on those three concepts, the most relevant of the language concept is from Noam Chomsky because he said that by knowing a language means
being able to produce an infinite number of sentences that never spoken before and to understand sentences that never heard before.
2.2.2 The concept of First Language Acquisition
According to Bowerman 2007, the first language acquisition is the determining how children learn to talk and understand, while the goal of
linguistic typology is to discover deep regularities in patterns if variation across languages.
According to Crain Lillo-Martin 1999, the language acquisition is the process by which humans acquire the capacity to perceive, produce and use
words to understand and communicate. It involves the picking up of diverse capacities including syntax, phonetics, and an extensive vocabulary. However,
learning a first language is something that every normal child does successfully without much need for formal lessons. Language development is also a complex
and unique human quality but yet children seem to acquire language at a very rapid rate with
most children’s speech being relatively grammatical by age three. Based on those two concepts of the first language acquisition, the most
relevant with this study is the concept of Crain and Lillo-Martin. It is because the concepts said that the first language acquisition is not obtained from formal
lessons but also it could be obtained from their environment. It relevant with this study, since Tonya as the intermarriage child could obtain her first language by
her environment.
