The concept of diglossia in Caribbean creole situationsDonald Winford (1985).Language in Society, </div><div> ">Volume 14, Issue 03, September 1985 pp 345-356 http://journals.cambridge.org/action/displayAbstract?aid=2991788 When finishing the chapter 1 of Mesthries Introducing Sociolinguistics, there is a big question in my mind about diglossia. This question comes into mind when I think about my dialect in my home country, Indonesia. I was brought up in a town in Birds head peninsula in West Papua, Indonesia, and when I was a child, I thought that I spoke Indonesian language. However, in fact, the language that I have spoken that merely a dialect called Papuan Malay; this term coined several years ago when there were some linguistic researches about the language spoken in my area. For your information, in West Papua area, I study the national language known as Bahasa Indonesia. Bahasa Indonesia, to some extent, is known as the modern modified Malay with abundantly loanwords from Sanskrit, Portuguese, Spanish, Dutch, Chinese, Arabic, English, and other tribal languages. I have studied and learned Bahasa Indonesia since I was in primary school, while when I was at home, my family and I as well as the community around me spoke the dialect known as Papuan Malay; it has served as the lingua franca of trading in the area to communicate with tribes in West Papua since circa 17th centuries or before the integration to Indonesia. Bahasa Indonesia, otherwise, is the language used at school, government, and any formal situation especially concerning to academic writing.Mesthries explanation about Fergusons Diglossia and Fishmans extension (Mesthrie, 2009: 39 40), to some extent, makes me think about my dialect and national language Bahasa Indonesia, whether Papuan Malay is simply a dialect in terms of standard versus dialect arrangement or the situation when the diglossia occurs? I also wonder about the possibility that one dialect, at first is just a dialect in such non-diglossic society but when there is a change in society, lets say because of political circumstance leading to diglossia occurrence, or vice versa. Is that possible?Regarding to the hints in the textbook, the two distinctions proposed by Ferguson about diglossia can be used to describe the situation of the dialect used in my area especially the second hint that mentions the relationship between standard and dialect is typically a close one, and it is not always easy to draw the line between the two. Again, in contrast the H and L forms of diglossia have distinct grammars which are almost like those of different language. (Mesthrie, 1999: 39). It is because, in the case of Papuan Malay comparing to Bahasa Indonesia, it is so easy to distinguish between the standard and dialect, for example in terms of its morpho-syntactical structure. It is really clear, letsay, when addressing question to another person as well in addressing the possession of someone.To illustrate my questions, I would like to give two simple sentences and its literal gloss written in my dialect and in Bahasa Indonesia (both formal and informal) about the case of interrogative form and possessive pronoun. In my dialect, we cannot form
