Format of article and letter  

Articles

• Depending for what purpose you have to write an article on, your beginning will vary. 
• However, for any article, you have to keep in mind the fact that you address the 5Ws and 1H- What, When, Why, Where, Who, and How. 
• Once you have these 6 things in place, you have to ensure your article has a structure. Usually while writing news articles, (which also holds true for a general article), following an inverted pyramid structure is advisable. An inverted pyramid structure basically means there will be an introduction, body and conclusion to the article. 
• Keep your sentences short, and crisp. 
• Give headings, sub-headings wherever necessary. But do not over do it. 
• Your headline (title of the article) should be short as well. Maximum 7 words. 

A) Formal Letters:

• Address the concerned person, along with his/her full address
• Write the present date 
• Give a Subject Line that should briefly talk about the purpose of the letter
• Address the person with salutation
