Answer:
An informal letter is a letter you would write to a friend, a family member or an acquaintance. The classic informal letter has five parts as follows:
1. Address Block Includes your return address and the date of writing the letter. This block is usually right-justified.
2. Opening Salutation This is the opening greeting; typically "Dear John". Left-justify this block.
3. Body Block This is your actual letter content (introduction + main parts + final paragraphs). It can be anywhere from a few paragraphs in length up to multiple pages. In the exam the length of the letter will be defined in the task (usually somewhere between 120 and 180 words). The body paragraphs should be left justified.
4. Closing Salutation This is where you say goodbye. Typically, closing salutations for informal letters include such phrases as: "Yours truly,", "Your friend,", "All the best,", Take care,". These days, more informal closing salutations are also acceptable, such as: "See you soon,", "Don't be a stranger,", etc. Left-justify the closing salutation.
5. Signature Block Since it is an informal letter to someone who knows you reasonably well, just sign your first name. Also left-justify this block.
