What Is an Informal Letter?
An informal letter is a letter that is written in a more personal, intimate, and conversational tone. It is more relaxed than formal letters, and its language and structure don’t necessarily follow correct English grammar rules. It also does not contain the same standard structure as formal letters. When writing an informal letter, the writer should think about who will be receiving it and what kind of message they would like to communicate.
Informal letters often include sentimental or personal topics—such as family news or vacation stories—and focus on relationships between the writer and recipient. In addition to being more conversational, they usually contain slang words, abbreviations, and emoticons to convey a relaxed feeling.
The main purpose of an informal letter is to keep in touch with family members, close friends, and other people you are familiar with but may not have seen recently. In this way, informal letters can help maintain relationships over time by keeping people in touch with each other’s lives.
How to Start an Informal Letter
When starting an informal letter, it’s important to establish a connection with the recipient and make them feel comfortable. Start by greeting them in a familiar manner. This could be a simple “Hi [name]”, “Dear [name]”, or a more informal version such as “Hey [name]” or “What’s up [name]?” It’s important to remember to use their name in the greeting so that it feels more personalized.
Then, move on to the body of your letter. It helps to think about the purpose of your letter and structure your thoughts accordingly. For example, if you are writing to update someone on recent events, start with a brief overview of those events before getting into details. You can also use this opportunity to address any topics of importance you discussed in previous conversations or add any other information they might find interesting.
Finally, end your letter by restating how much you value their friendship or relationship and make sure they know that they can always reach out if they need anything.
How to Format Your Letter
Informal letters tend to follow a more relaxed formatting style than formal letters. Here are a few tips on how to correctly format your informal letter:
Heading
Start with your address and the date below it. You may also add a reference line above your address.
Salutation
Use the word “Dear” and then the recipient’s name, followed by a comma (e.g. “Dear John,”). You can also use terms such as “Hi,” “Hello,” or “Greetings.”
Body
The body is the main content of your letter and should include any information that you want to convey to the reader. Break up your text into shorter paragraphs and explain each point clearly in as few words as possible. Make sure to include examples or supporting evidence for any claims that you make in the body of your letter.
Closing & Signature
End with an appropriate closing such as “Sincerely,” or “Yours truly,” followed by a comma and then your full name below that. You can also add additional comments such as “PS: please let me know if you have any questions!” at the end of your letter before signing off with your name.
Writing Style for an Informal Letter
When writing an informal letter, it’s important to use a friendly and natural language that is reflective of the relationship between you and the recipient. This can be achieved through the use of simple words, short sentences, and light humor. Here are some tips on how to write an informal letter in a friendly, conversational style:
Greeting
Address the recipient with an appropriate salutation, like “Hello” or “Hi”. Avoid overly formal salutations like “Dear Mr./Miss/Mrs.”
Tone
Write as if you were talking to someone in person; use short sentences and friendly terms that express your feelings about the subject. Avoid using complex words or complicated terms that may confuse the reader.
Mention Positive Things
Mention anything positive about your relationship with the recipient or any shared experiences you may have had together. Doing so will make your letter more personal and will ensure that it stands out from formal letters.
Speak from Your Heart
Let your feelings show through in your letter. If you are expressing disappointment or anger towards someone, make sure to be direct but respectful in expressing yourself. Similarly, if you are writing out of love or gratitude, express those feelings clearly and sincerely without going overboard.
The Right Way to Sign Off an Informal Letter
Signing off an informal letter is an important step in the letter-writing process and deserves your attention. There are a variety of ways to end your informal correspondence, each expressing a different sentiment.
Traditional Closings
The most straightforward approach to closing an informal letter is with a traditional sign off such as “Sincerely,” “Warm regards,” or “Take care.” This type of closing will convey an overall polite tone and may be suitable for any situation.
Familiar Closings
If you know the recipient well, you can personalize your sign off with a greeting or expression that reflects your relationship. Examples include “Best wishes,” “Love” or even using their first name.
Humorous Closures
Depending on the context and relationship you have with the recipient, it can be appropriate to close with something more lighthearted like “Until next time!” or “Be excellent to each other!” Keep in mind that these should generally be reserved for people whom you know well, lest they come across as too casual or disrespectful.
No matter which closing you choose, taking the time to properly finish your informal letter will help show respect and appreciation for the reader.
