are elements in a language component Dulay, Burt, and Krashen, 1982:281. Indefinite articles, noun phrase, and verb phrase are some parts of linguistic
categories in the grammars. Linguistic category taxonomy contributes to the distributions of errors. This
research takes the theory of Politzer and Ramirez 1973 reviewed by Dulay, Burt, and Krashen. Politzer and Ramir
ez’s theory analyzes the grammatical errors on two linguistic features which are morphology and syntax.
a. Morphological Analysis
In the morphology, the errors are classified into six categories. It focuses on
the analysis of word structure. The classifications are presented as follows: i. Indefinite Article Incorrect
The first category is indefinite article incorrect. The error focuses on the mistake of article use between article a and article an. The example is an ball. In this
case, the error occurs when the article an is used before consonants 1982: 148.
ii. Possessive Case Incorrect
The second category is possessive case incorrect. The example of this category is this book is your. In this case, there is an omission of suffix -s after the
word your. Yours means that the pronoun you has a possessive right towards the book 1982: 148.
iii. Third Person Singular Verb Incorrect
The third category is third person singular verb incorrect. The example is the sun rise on the east. There is an omission of suffix -s that influences the word
formation of main verbs. Based on the example, the sun is categorized as third person singular. Thus, the main verb should be added suffix
–s which is rises 1982: 148.
iv. Simple Past Tense Incorrect
The fourth category is simple past tense incorrect. This category has two types of errors. They are regular past tense and irregular past tense. They are explained as
follows: a. Regular Past Tense
In this type of errors, it focuses on the analysis of word formation for regular verbs. The example is I save my sister from the accident yesterday. The error
occurs due to the omission of –ed. The omission of –ed influences the word
formation in the past tense structure. Thus, it should be saved 1982: 148.
b. Irregular Past Tense In this type of errors, it focuses on the analysis of word formation for irregular
verbs. The example is I maked a cake. In this case, maked is incorrect because the past form of make is made. It is categorized as irregular form. Thus, it
should not be added by suffix –ed. 1982: 148.
v. Past Participle Incorrect
