Limitation of the Study

Heidi Dulay said that errors are the flawed side of learner speech or writing. They are those parts of conversation or composition that deviate from some selected norm of mature language performance. 4 We use “error” to refer to any deviation from a selected norm of language performance, no matter what the characteristics or causes of the deviation might be. According to Peter Hubbard et al, so far all incorrect forms produced by the student we have called “errors”. 5 Carl James defines Error Analysis as the process of determining the incidence, nature, causes and also the consequences of unsuccessful language. 6 According to H. Douglas Brown, The fact that learners do make errors, and that these errors can be observed, analyzed, and classified to reveal something of the system operating within the learner, led to a surge of study of learners’ errors, called error analysis. 7 So, in this study the writer would like to observe, analyze and classify learner’s error in mastering regular and irregular verbs.

2. Types of Error

Basically, there are many classifications about types of errors in learning English that classify by Corder and Heidi Dulay et, al. According to Corder, errors are classified into four basic such as errors of omission, errors of addition, errors of selection, and errors of ordering. If some element is omitted which should be present, it is called errors of omission. If some element is present which should not be there, it is called errors of addition. Next, if the wrong item has been chosen in place of the right one, it is called errors of selection. And the last, where the elements presented are correct but wrongly sequenced, it called errors of ordering. 8 4 Dulay, et al., op. cit., p. 138 5 Hubbard et al., op. cit., p. 136 6 Carl James, op. cit., p. 1 7 Brown, op. cit., p.259 8 S.
