Lexical and Grammatical Ambiguities In Engligsh Texbook For Tenth Grade Students

This study dealt with effort of finding the lexical and grammatical ambiguity in English textbook of Bahasa Inggris for the tenth grade. The objectives of the study were to find out the types of ambiguity and to find out the dominant types of ambiguity in Bahasa Inggris of the tenth grade. The numbers of the data were 21 of reading texts which were taken from English textbook of Bahasa Inggris of the tenth grade. The types of ambiguities were identified based on Fromkin et al theory. The research design used in this research is descriptive qualitative. The data were analyzed by Identifying , classifying, tabulating and interpreting. From 21 reading texts, there were 27 sentences that contained ambiguous meaning. There are two types of ambiguity found in reading texts, they were lexical and grammatical ambiguity. The lexical ambiguity consisted of homonym, polysemy and antonym. While grammatical ambiguity consisted of coordinate structure, negation scope, active or passive meaning, gerund + object or participle modifying a noun, prepositional phrase (PP) as modifier or sentence adjunct, and a head of inner modifier and outer modifier.

INTRODUCTION
When a word, phrase or sentence can be defined in many ways it might have high potential to ambiguity. Ambiguity is words or sentences which have more than one possible meaning in language. According to Kreidler (2002) states ambiguity as the condition where by any linguistic form has more than one interpretarion. Quite similar, Hurfoford and Hesley (2007) says ambiguity arises if it has more than one paraphrases which are not themselves paraphrases of each other. In social interaction, language is very vital. Language is used to express the feelings, ideas, thoughts, opinions, emotions and willingnes. Language has meaning. Meaning is conveyed by either spoken or written.
Conveying meaning by spoken language is far different with written language. Spoken language is two ways communication where both speaker and hearer can interact directly. Whereas written language is only one way communication, so when the readers do not understand they cannot ask directly. Written language is more difficult to understand since sentence structure in written language more complex. If the words, phrases or sentences are used inappropriately way, the meaning will be ambiguous. According to Cruse (1986:66) divides ambiguity into four types: pure syntactic ambiguity, quasi-syntac ambiguity, lexicosyntactic ambiguity, and pure lexical ambiguity. Ambiguity is grouped into three according to Kess(1992:133) they are are lexical ambiguity, surface sructure ambiguity and deep (underlying) structure ambiguity. Whereas, Fromkin et.al. (2017;83) classifys ambiguity into lexical and structural ambiguities. Structural ambiguity is also called as grammatical ambiguity.
As explained above, it can be simplified that ambiguity is divided into lexical and grammatical ambiguity. principally, if a word, phrase or sentence which has more than one interpretation is called ambiguity. Sometimes one word could consist more than meaning or one meaning of a word could dirive from onother word. Lexical ambiguity is divided into three: homonymy, polysemy, and synonym. Whereas, a sentence which has more than one structural sentence tree is called grammatical ambiguity. There are six type oof grammatical ambiguity: coordinate structure, negation scope, active and passive meaning, gerund + object or participle modifying a noun, prepositional phrase (PP) as modifier . Now days, ambiguity is a serious concern as it can intrude the communication either in spoken or written language.
As it can be seen there are a lot of printed media like newspapers, magezines advertisments and so on consist the sentences with ambiguous meaning. This case indicates that many researchers have shown great interests in ambiguity. Julie Puspitasari et.a (2019)l anaylzed lexical and structural ambiguity in article in the Jakarta Post daily newspaper by using Macmillan dictionary to find the defenition of each word in exical ambiguity and label and bracketed sentences/ phrases proposed by Yule were used to analyzed data. Quite similar, Bustam (2012) examined ambiguous structure through the structural ambiguity concept. The paper purposed to find out a clear description of structural ambiguity. Furtheremore, the result of the paper, showed that the structural ambiguity can find in structural ambiguity, such as noun phrase, prepositional phrase, relative clause, noun clause, and also comnination of those with conjuction (coordinate). In the same erea of semantic, Rulik Setiani (2019) investigated ambiguity in students' writing assay.
This paper showed that amiguity was found in students' writing assy due to the sentence strurture were inappropriate and the words used were less correct. Similarly, Anggur (2019) analyzied lexical and grammatical ambigyutiy and what factors that effect the witting skills of primary 4 students of Champion Denpasar-Bali. Moreover, Basil examined the lexical source of ambiguity in English and daily communication by using lexico-semantic concept. The issue of ambiguity is very serious since it can intrude the communication. Based on the fact, both language teachersa and learners musthave on significances of how to build a good grammaticcal ambiguity, Almahameed (2020). According to Kurniasari (2017) to tolerate the ambiguity is by getting better understanding toward the language itself. Masda S.S (2007) resolve the ambiguity by using formal signal, function words, stress, jucture, inflection, and affixes. Similarly, Robert Milne (1986) found the resolution of lexical ambiguity by presenting dtrministic parshing with a major test.
This study is conducted to find the ambiguity in English textbook of Bahasa Inggris of the tenth grade. This study only focuses on occurrences of lexical and grammatical ambiguity in Bahasa Inggris of the tenth grade. A textbook is a compulsory media in language learning especially for foreign students where English is not their native language. An English textbook provides English four skills: writing, listening speaking and reading. All these skills must be mastered by the students. From four skills, reading is the most difficult since reading is the process of understanding the meaning of words, ability to interpret meaning of word based on the context and ability to recognize the literary devices or propositional structure.
Reading involves to the text. Some texts may consist words, phrase or sentences which are arduous to be understood due to the of words, phrase, or sentences used have several possible meanings. This phenomenon is called ambiguity. If the words, phrase or sentences in the text have more than one meaning, it may cause a misunderstanding for the students who read it. Ambiguity is not tolerated in a textbook, especially English texts cause it can make the students confused. If the students do not understand the content of the book, the target of leaning is failed. Students of Indonesia are mostly not influent in English since English is as a foreign language for them. English textbook is one of media that mostly used to learn English at school. Therefore, English textbook must be written with the language which is easy to be understood by the students. But in fact, there were some English textbooks which consist ambiguous meaning.
Based on the problem above, the writer analyzes lexical and grammatical ambiguity in English textbook. The writer only focuses on Bahasa Inggris of the tenth grade. This study is expected to identify and classify the occurrence of lexical and grammatical ambiguity. This study is conducted to find the types of ambiguity occurrences in English textbook of Bahasa Inggris of the tenth grade. Moreover, this research also interpret the meaning of words, phrases or sentences which are possibly ambiguous.

Lexical ambiguity
From 21reading test of English textbook of Bahasa Inggris of the the tenth grade. The writer found 12 words caused by the lexical ambiguity. The data shows that the all the types of lexical ambguity found in English textbook. Where 7 occurences due to homonymy, 2 occurences caused by polysemy and 3 occurences were found in synonym.

Extract 1 "Habibie's government stabilize the economy in the face of the Asian financial crisis" The sentence above tells B.J Habibie. This sentence is ambiguous meaning caused by homonymy. The ambiguity of the sentence can be seen from the word "face". This word may lead the readers into wrong interpretation.

Extract 3 "Suharto requested Habibie to return to Indonesia as part of Suharto 's drive to develop the country" The word " drive" is considered as ambiguous caused by homonymy. Based on Oxford Electronic Dictionary , "drive" has multiple meaning "operate and control the direction and speed of motor vehicle", "people or carry along by force in a specified direction", and "an organized effort by a number of people to achieve particular purpose".
Based on interpretation above, the most appropriate meaning by the text is "an organized effort by a number of people to achieve particular purpose", which can be interpreted into "Suharto requested Habibie to return to Indonesia as part of Suharto's effort to develop the country" the text tells about Habibie was successed in Germany. It was proven by his some achievements. Extract 4 "At dawn when the first rays of the sun hits the dome of this epic monument, it radiates like a heavenly pinkish palace".
