I never write a whole writing essay in my language, because we don’t practice, we stop taking writing Arabic class from 9th grade from the first grade, until 9th grade was all about description, and story telling essays. After that no more Arabic writing! We usually do English writing from high school until we die.
We think it’s more professional, and academic since everyone understand it, and especially when your instructor or the other partner is international, English writing is more important than Arabic we think.
In university I use to learn how to write academic essay, and then I start applying it in my final exams for all subjects, without evening noticing, through explaining some concepts and formulas.
To conclude that, maybe some Arabs writs poems and articles, but me I don’t since I don’t have this hobby, and didn’t develop it at all!
