Which of the following best describes an effective letter?

An effective letter is characterized by being clear, concise, and correct. Clarity ensures that the message is easily understood by the recipient, which is essential for effective communication. Conciseness helps to convey the main points without unnecessary elaboration, allowing the reader to grasp the important information quickly. Furthermore, correctness encompasses not only accurate information but also proper grammar and spelling, which contribute to the professionalism of the correspondence.

Long and detailed letters may overwhelm the recipient and dilute the main message, making it harder for them to focus on the key points. Letters filled with jargon can alienate readers who may not be familiar with specialized terms, hindering effective communication. Lastly, letters that focus only on technical terms could fail to engage the recipient or convey the intended message clearly, leading to misunderstandings. Thus, clarity, conciseness, and correctness are essential characteristics that contribute to the effectiveness of a letter.
