They stick to a structured format, use formal greetings and salutations, avoid abbreviations, and follow a clear introduction, body, and conclusion. Formal letters often require documentation, end with a formal closing, and are signed by the sender.

10 Main differences between formal and informal letters (Detailed explanation)
1/ Tone and language:
Formal Letters: Formal letters require a professional tone and language. They are typically used in business, academic, and official settings. The tone should be respectful and courteous, maintaining a sense of professionalism throughout. Language should be formal, using standard grammar and avoiding slang or colloquial expressions. The goal is to convey information clearly and professionally.
Informal Letters: In contrast, informal letters have a more conversational tone. They are typically used when writing to friends, family members, or acquaintances. The language used can be more relaxed and casual, allowing for personal expressions and informal phrases. Slang, abbreviations, and contractions are commonly used to create a friendly and relaxed atmosphere.
2/ Structure and formatting:
Formal Letters: Formal letters follow a standard format to maintain professionalism and clarity. They typically include the sender’s and recipient’s addresses, dates, subject lines, and a formal salutation. The letter’s body is structured into paragraphs, with each paragraph dedicated to addressing a specific point. A formal closing phrase is used, followed by the sender’s signature and printed name. The structure ensures a logical flow of information and makes it easier for the recipient to navigate the content.
Informal Letters: Informal letters possess a flexible structure in contrast to formal letters. While there is no strict format, they usually consist of an introduction, body, and conclusion. The structure can be less formal and more relaxed, allowing for a free-flowing conversation-like style. Informal letters may not include addresses, subject lines, or formal salutations. The closing can be more casual and personalized, depending on the relationship with the recipient. The purpose is to convey thoughts and feelings in a less structured manner.
3/ Audience and purpose:
Formal Letters: Formal letters are typically written for professional or official purposes. They are directed towards individuals or organizations with whom you have a formal or business relationship. The audience for formal letters includes employers, colleagues, government officials, academic institutions, or other formal entities. The purpose of formal letters can vary widely, such as applying for a job, making a complaint, requesting information, or submitting official documents. The tone and language used in formal letters are tailored to maintain professionalism and respect.
Informal Letters: Informal letters are usually intended for personal connections, including family members, or acquaintances. The audience consists of individuals with whom you share a more casual and informal relationship. The purpose of informal letters is often to catch up, share personal news, express emotions, or simply engage in friendly conversation. Informal letters provide the opportunity to showcase your personal voice and connect on a more personal level.
4/ Use of greetings and salutations:
Formal Letters: In formal letters, the use of greetings and salutations follows a more structured and respectful approach. Common formal greetings include “Dear Mr./Ms./Dr.” followed by the recipient’s last name. If the recipient’s gender is unknown, it is acceptable to use the full name without a title. For example, “Dear Alex Smith” or “Dear Jordan Taylor.” The salutation at the end of the letter is typically more formal, using phrases such as “Yours sincerely” or “Yours faithfully” followed by the sender’s full name.
Informal Letters: Informal letters allow for a more relaxed and casual approach to greetings and salutations. Depending on the relationship with the recipient, informal greetings can include variations like “Hi [Name],” “Hello [Name],” or even a simple “Hey.” For close friends or family members, more informal greetings like “Dear [Name],” “My dearest [Name],” or even using nicknames are common. The salutations in informal letters are more flexible and can range from casual phrases like “Best regards” or “Take care” to more personalized closings like “Love,” “Warmly,” or simply signing off with the sender’s first name.
5/ Length and level of detail:
Formal Letters: Formal letters generally require a more concise and to-the-point approach. They tend to be more structured and focused on conveying specific information or addressing a particular matter. The length of formal letters varies depending on the complexity of the subject but is typically kept within a reasonable limit. The level of detail provided in formal letters is sufficient to communicate the necessary information without excessive elaboration. Clarity and precision are prioritized in order to maintain professionalism and avoid ambiguity.
Informal Letters: In comparison, informal letters allow for greater flexibility in terms of length and level of detail. They can be shorter or longer, depending on the purpose and the depth of the conversation. Informal letters frequently incorporate personal experiences, facilitating a relaxed and informal writing style rather than formal writing. The level of detail can be more extensive, as the purpose of informal letters is often to share experiences, emotions, or thoughts in a more expressive and conversational manner.
6/ Use of contractions and abbreviations:
Formal Letters: In formal letters, the use of contractions (such as “don’t,” “can’t,” and “won’t“) and abbreviations should be avoided. The focus is on maintaining a professional and precise tone and using full words and phrases is preferred. This helps ensure clarity and avoids any potential confusion or misunderstandings.
Informal Letters: Informal letters allow for the use of contractions and abbreviations, as they contribute to a more casual and conversational style. Contractions like “don’t,” “can’t,” and “won’t” are commonly used, as well as abbreviations like “LOL” (laugh out loud), “BTW” (by the way), or “OMG” (oh my god). These informal language elements add a sense of familiarity and informality to the letter, reflecting a relaxed and friendly tone.
Valuable Tip: When deciding whether to use contractions and abbreviations, consider the level of formality desired in the letter and the nature of the relationship with the recipient.
7/ Proofreading and editing conventions:
Formal Letters: Formal letters require careful proofreading and editing to ensure accuracy, clarity, and professionalism. Reviewing the letter for spelling, grammar, and punctuation errors is essential. Attention should be given to the proper use of capitalization, consistent formatting, and adherence to formal writing conventions. Proofreading helps to eliminate any potential mistakes or ambiguities that may detract from the professionalism of the letter.
Informal Letters: While proofreading is still important in informal letters, the level of strictness may be more relaxed. Informal letters allow for a more conversational and casual style, and minor errors may be more forgivable. However, it is still advisable to review the letter for any glaring mistakes or miscommunications.
8/ Use of formal or informal sentence structures:
Formal Letters: In formal letters, the use of formal sentence structures is preferred. This includes using complete sentences with proper subject-verb agreement and clear, concise language. Formal sentence structures ensure clarity and professionalism in communication. Avoiding sentence fragments and run-on sentences helps maintain a formal tone and effectively conveys the intended message.
Informal Letters: In informal letters, sentence structures can be more flexible and varied. Informal writing allows for the use of conversational sentence structures, including fragments, colloquial expressions, and even the occasional use of incomplete sentences. Informal letters often mirror the natural flow of conversation and reflect a more relaxed and casual style.
9/ Cultural and contextual considerations:
Formal Letters: In formal letters, it is important to consider cultural and contextual norms. Different cultures may have specific expectations regarding language, etiquette, and formality in written communication. Understanding and respecting these cultural nuances is crucial to ensure effective communication and avoid any unintentional misunderstandings or offenses.
Informal Letters: In informal letters, cultural and contextual considerations are still relevant, but they may have less impact compared to formal letters. The level of formality and cultural nuances can vary depending on the nature of the relationship and the familiarity between the sender and recipient.
10/ Documentation and references (e.g., citations, footnotes):
Formal Letters: In formal letters, especially those related to academic or professional contexts, it may be necessary to include documentation and references to support claims or provide additional information. This includes citing external sources, referring to relevant research or literature, and providing proper attribution when using someone else’s work or ideas. Additionally, depending on the field or organization’s requirements, formal letters often follow specific citation styles, such as APA (American Psychological Association) or MLA (Modern Language Association).
Informal Letters: In informal letters, the need for formal documentation and references is generally less common. Informal letters tend to focus more on personal experiences, opinions, and casual conversations rather than citing external sources. While informal letters may still reference shared experiences or previous conversations, the need for formal citation styles or footnotes is typically unnecessary.
