The essay has a basic structure with an introduction, body, and conclusion. However, the organization of ideas is not clear, and there is no logical progression in the letter. The use of cohesive devices is limited and sometimes inaccurate, making the overall flow of the letter choppy and disjointed. Transitions between sentences and paragraphs are weak, which affects the readability of the letter.

Suggestions

• Use a variety of cohesive devices correctly to improve the flow of your letter.
• Make sure each paragraph has a clear central topic and that all sentences in the paragraph relate to this topic.

The letter uses a range of vocabulary, but there are several instances of incorrect word choice and awkward phrasing. Spelling and word formation errors are present, which occasionally hinder understanding. The vocabulary used is generally simple and may not be sufficiently varied or precise.

The letter contains a variety of grammatical structures, but there are numerous grammatical errors that can cause confusion. Punctuation is often misused or missing, further affecting the clarity of the message. Some sentences are overly complex or awkwardly constructed, making them difficult to understand.

The letter addresses the task, providing an explanation for not having returned the book and expressing a desire to apologize and make things right. However, the explanation is somewhat unclear and could be more structured to effectively communicate the main points. The letter mentions returning the book on a specific date but does not provide clear instructions or conditions for the return. The inclusion of an offer to exchange books is a bit confusing and not well-integrated into the main argument of the letter.

Suggestions

• Make sure your main points are clear and well-supported in your letter.
• Keep the book exchange offer relevant and straightforward to avoid confusing the reader.
