In composing process of commercial letters, we need a clesr paragraph composition. According to my knowledge, there has not any research about Indonesian Commercial letters paragraph composition, yet. Therefore, I observe this issue. Some problems that may come up in my observation are the theme development of the letters, the connection between paragraphs, and the material s that have been used.
The goal of this observation is to give some description about
Indonesian commercial letters paragraph composing, that is the development of the main ideas or the letters themes, harmonization of the connection between the sentences.
This observation use thoroughly approaching method. The content of the trading mails was supposed to be one whole unit. After read all the commercial letters, I analyzed the elements that composed the mails, then I find the relation semantically, lexically, and grammatically. These observation files are in the grammar files form which related to commercial letters, including introduction letters, offerrequest, offerings, demands, and orders delivery from the private companies. All files werw collected by a content analysis, that is collecting all commercial letters from the private companies and then the letters werw selected and sorted, make a note of the themes development, the marker of the relation between sentences the marker of the relation between paragraphs semantically, lexically, and grammatically, including all kind of the commercial letters which was mentioned above.
The observation result shows that there are tendencies that the letter is paragraphs content by 2 and 3 paragrafs, that is opening and closing paragraph, or opening, connector, and closing paragraph. Opening paragraphs always content by 1 paragraf, so that the cosing paragraphs, except on the 2 letters, that the closing paragraphs content by 2 paragrafs. The main ideas of each paragraphs content by 1 idea. There are some tendencies that every paragraphs was made by 1 sentence, so the letter is idea is only a development of one single sentence. A commercial letter which its paragraphs idea was developed deductively, the relation between sentences always subordinative. A commercial letter which its closing paragraphs content by 2 sentences, the relation between sentences always coordinative. The relation between paragraphs and sentences semantically, lexically, and grammatically always used by commercial letters to create a harmonize reading. There are tendencies that the relation between paragraphs always coordinative. The semantic ways between the paragraphs which used by the letters are the relation of reason-result, the ways-the goal, the conditions- the result, additives (not the time additives), and time additives. There are some tendencies that relation between paragraphs that have been used semantically are the relation of reason-result.
