The reconstructed utterance is based on our interpretation of what the students was trying to say. The problem is that we do not know what construction
the learner intended. For that reason, corder suggests solution depending on whether we have access to the students or not. Firstly, if the students present we
can ask them what they intended to say to make authoritative reconstruction, it called authoritative interpretation. Then, if the students are not available for
consultant, we have to attempt an interpretation of their utterances base on its form and its linguistic and situational context.

Since the point of this study is analyzing the students’ errors on the form and the usage of degrees of comparison, it is not difficult to interpret what the
students want to express in their writing. So, the researcher focuses on the transformations of the adjectives in making comparative or superlative degree.
Moreover, many issues arise in identifying students’ errors; one of them is whether a distinction should be made between errors and mistake. In fact, the
researcher has explained the definitions about errors and mistakes in the previous session; although, she will give more explanations about the differences between
them. Errors arise as a result of lack of knowledge, besides mistakes arise as a result of memory limitations, competing plans, and lack of automaticity. Corder
argues that errors analysis should be restricted to the study of errors, and mistakes should be eliminated from the analysis.

c. Description of Errors
In analyzing learners’ errors, some linguist makes some classifications of errors. Here are four categories Dulay, Burt, and Krashen classified omission,
addition, misformation and misordering.
21
Firstly, omission errors occur when an element of the sentence that should be presented is omitted or by the absence of an item that must appear in a well-
formed utterance, and it often occurs in form of morphemes. There are two main types of morphemes: lexical morphemes and grammatical morphemes. Lexical
morphemes consist of referential meaning of the sentence such as noun, verb,

adjective, adverb in the sentence. However, grammatical morphemes, include noun and verb inflections, plays a minor role in conveying the meaning of the
sentence.

Omission Errors

Omission of preposition: to

York Omission of Progressive
-ing I am play with it
I am playing with it
Note: - Symbol is omission - The bold printed sentences are adopted from Dulay, et al.
Secondly, addition errors are the opposite of omission errors. It is a phenomenon in which a certain aspect of language rules is added into a correct
order correct sentence. In order words, some elements are presented in which it should not be presented.

Addition Errors

The books is here The book is here.
Addition of present indicative s

Addition of direct object the hat

Addition of auxiliary did
John wasn’t
did swimming
John wasn’t swimming Addition of regular past
ed I didn’t played with it
I didn’t play with it
Note: -The underlined letter or word is addition - The bold printed sentences are adopted from Dulay, et al.
Thirdly, misformation errors are characterized by the use of the wrong form of the morpheme or structure. In other words, the error of using one grammatical
form in the place of another grammatical form or the learner supplies something,
although it is incorrect. Table 2.3

Misformation of auxiliary did

Misformation of preposistion at

Misformation of reflexive pronoun
hisself He is licking hisself

Misformation of indefinite article an
it is an book It is a book
Note: - The underlined word is misformation - The bold printed sentences are adopted from Dulay, et al.
Finally, misordering errors occur when a sentence which its order is incorrect. The sentence can be right in presented elements, but wrongly
sequenced.
