I'm writing an apology letter for missed class. Which of the following should I use?

  • I had not being able to attend the class.
  • I not having been able to attend the class.

If both are ungrammatical, is there any other way to express this?

When I searched for answers, I got more confused. I couldn't find any legitimate solution, and I'm not sure if the sources can be trusted or not. Can anyone help me on this?

    The first one is ungrammatical, and the second one can only work as a (borderline ungrammatical) dependent clause.

  • @ЯegDwight Thank you. Is there any other way for expressing the situation.

  • A native speaker would say "I was not able to attend the class".

  • Is it okay if I write it in a letter for class teacher or principal.?

If you are writing a letter, and you missed a single class, use:

I'm sorry I was not able to attend class.

If you missed a series of classes, and you have not been back to class yet, and you want to allude to the ongoing practice of missing class, use:

I'm sorry I have not been able to attend class.

That second sentence might be better if you were unable to attend class for a more prolonged period of time. It sounds like the wording you might have been fishing for.
