Informal Letter outline:

A letter is a formal and personal way to communicate with someone. It is different from an email or a text message because it is more personal and usually more formal. There are many ways to write a letter, but you should keep in mind that the most important thing about writing a letter is that it should be written in an informal tone.

The following are some of the best ways to write an informal letter:

  • Start by introducing yourself and your relationship with the person you are writing to.
  • Write about what you have been doing recently and how you feel about it.
  • Write about something that happened recently or share your thoughts on something that happened long ago.

The Importance of Formal vs. Informal Letters

The first thing to keep in mind when writing a letter is the format. There are two formats for letters: 1. Informal and 2. Formal. In an informal letter, you can use contractions and abbreviations, but in a formal letter, you should avoid them. The second thing to keep in mind is that you may use first-person or third-person writing. In a formal letter, you should use the third person – the letter is from “John” and “I” refers to John. In an informal letter, the person can be used more frequently because it’s not formal communication.

What Can You Write about in an Informal Letter?

An informal letter is a letter that does not have to be formal and can be written in a more conversational style. The tone of an informal letter is usually less formal than the tone of a business letter, but can also be more formal than an email.

There are three basic parts to an informal letter: the address and date, the forms of greeting/salutation, and the introduction followed by body paragraphs.

Format for Informal Letter-

Informal letters don’t have a specific format. However, there is a basic pattern, or set of rules, that most individuals adhere to. This pattern, as well as some advice on how to create successful and appealing casual letters, will be discussed. Although there are no hard and fast rules, they can be utilized as guidelines when drafting a letter. The format listed below should be followed while the letter writing so that it seems appealing to the receiver. When writing a letter, these rules are often followed.

  • Address –The sender’s address should be written first. This is written in the upper left corner of the page and acts as the letter’s beginning. It is required that you provide your entire address as well as your pin code. Even if it is an informal letter to friends and family, it is necessary to include the whole address so that the recipient may respond. If you’re writing a letter to someone who lives outside the nation, don’t forget to include the country’s name.
  • Date –Below the address, the date, i.e. the date on which the letter was written, must be written. The date on which the letter was written will be known to the recipient. The date should be extended as much as feasible.
  • Greeting – You may use a more casual greeting now that you know who you’re writing to. If you’re talking to a friend or someone your age, use their first name, such as “Dear Peter.” If you’re writing to a relative, such as your mother, father, uncle, aunt, or cousin, you might address them as such, like “Dear Mom.” You can address an elderly citizen or someone you admire as Mr. or Mrs. if you’re writing to them. “Dear Mrs. Parikh,” for example, maybe the salutation in a congratulatory letter to your professor.
  • Introductory Paragraph- After that, you’ll begin composing the letter itself. An introduction should be the opening paragraph of your letter. This will establish the tone for the rest of the letter. Begin the letter by inquiring about the health of the recipient. Likewise, you might write, “I hope you are well.” This is the letter’s first stage.
  • Body of the Letter- The letter’s tone should be friendly throughout. However, you’ll need to modify the language and phrasing depending on who you’re writing to. When you’re with a buddy, you may be casual and even sarcastic. However, while writing to an older relative, you must be respectful and polite. To assist you to set the tone of your letter, think about how you spoke to the person in a discussion. Then apply the same grammar and sentiments in your letter.
  • Conclusion – Summarize the purpose for drafting the letter in the last paragraph. Give the reader a sincere farewell. Also, don’t forget to remind the reader to reply in writing to your letter. It indicates that the individual wants to continue the conversation.
  • Signature – There isn’t a single method to end a casual letter. You may sign off as you like because they don’t follow a specific structure. You can sign off using some common phrases like Kind regards, Lots of love, Best wishes, etc. Choose a greeting that is appropriate for the situation and sign your name below that.

For official reasons, such as doing business, formal letters are expected and extensively utilized. Using them to communicate with friends and family, however, is not widely acknowledged. In comparison, informal letters may not automatically reflect a lack of decorum. In such letters, a more casual and natural style of discourse is utilized. Even informal letters might be held to high standards.

How to Write an Informal Letter?

Informal letters are less formal than formal ones. They are usually written to friends and family members, so they can be more personal and informal. It is also a good way to write when you want to get your point across quickly.

Mistakes to Avoid When Writing Informal Letter

Mistakes to avoid when writing an informal letter:

  1. Don’t use too many words or sentences that sound like you are bragging about yourself.
  2. Avoid using too much slang or informal language, as this can make your letter seem unprofessional.
  3. Don’t go into too much detail about your life story, as this will bore the person who receives the letter and take up time that could be spent on more important things.
