Response in English: A formal letter is typically written in a professional, polite and business-like manner. It follows a specific structure, and often follows a designated format, such as block or semi-block format, and uses formal language and tone to convey a message, request, or other communication. Formal letters are often used for business, employment, or official purposes, and may be addressed to an individual, company, organization, or a government agency. Examples of formal letters include job applications, cover letters, legal correspondence, and letters of complaint.On the other hand, an informal letter is typically written in a more relaxed, personal and conversational style. It does not follow a strict structure, and the language and tone can be more casual and friendly. Informal letters are often used for personal communications between friends or family members, and may be handwritten or typed. They are commonly used to convey personal news, express gratitude, congratulations, sympathy or share experiences, and may be addressed to someone the sender knows well. Examples of informal letters include thank you notes, invitations to a party, letters of condolence and letters to friends or family members.In summary, the key differences between formal and informal letters are the tone, structure, format, and purpose. Formal letters are used for professional or official communications, while informal letters are used for personal communications. .
