Formal:
* M̀ ga-ekwesịghị ịde n'asụsụ Bekee. (M ga-ekwesịghị means "I am not good at" and ịde n'asụsụ Bekee means "writing in English")
* M̀ nweghị ike ịde n'asụsụ Bekee nke ọma. (M̀ nweghị ike means "I am not able to" and nke ọma means "well" or "properly")
Informal:
* M̀ nweghị ike ịde Bekee nke ọma. (A shorter version of the previous formal sentence)
* M̀ na-agbalị ịde Bekee, mana m̀ ga-ekwesịghị. (Means "I am trying to write in English, but I am not good at it.")
You can also use a more descriptive phrase like:
* Asụsụ Bekee adịghị m̀ mma. (Means "English is not good for me.")
It's important to note that the choice of expression will depend on the context and the person you're talking to. For example, if you're talking to a friend, you can use a more informal expression. But if you're talking to a teacher or someone you don't know very well, it's best to use a more formal expression.
