F. Definition of Terms
In this part, the researcher defines the key words or phrases in order to clarify the concepts and avoid misinterpretation. The following definitions are:
1. Grammar
“Grammar is explained as a description of the structure of a languageas cited in Harris and Levey, 1975
”. Woods and Friedman 2010 explain that grammar is the study of language, specifically how words are put together.
Additionally, they state that grammar means a set of standards in writing. In this research, grammar means a set of standards in language that the writer has to
follow in order to produce correct grammar.
2. Error
Brown 1991 stateserror is systematic. The errors usually occur repeatedly and are not recognized by the learners. In fact, Brown 1987
mentionsthat it is crucial to make a distinction between mistakes and errors since mistake refers to a performance error that is either a random guess or a
“slip,” in that it is a failure to utilize a known system correctly p. 170. Brown 1987 emphasizes that it is not easy to explain the differences between an error
and mistake. In order to avoid the misunderstanding, the researcher concludes that the data found in this research refers toerror since the definition of error is a
systematic deviation that can be corrected and it is not realized by the learners.
