Dear Professor Johnson,

I hope this email finds you well. I am writing to request an extension for the upcoming assignment. 

I have been facing some unexpected personal circumstances that have greatly impacted my ability to complete the assignment on time. I understand the importance of meeting deadlines and strive to be a responsible student, but unfortunately, the circumstances are beyond my control.

I assure you that I am committed to completing the assignment to the best of my abilities. However, given the current situation, I would greatly appreciate
an extension of [insert number of days] for the assignment. This additional time will allow me to properly address the personal circumstances and ensure that I submit quality work.

I understand that granting an extension is at your discretion, and I genuinely appreciate your consideration. If there is any additional information or documentation that you require in order to support my request, please let me know and I will be more than happy to provide it.

Thank you for your understanding and support during this challenging time. I look forward to
