學什麼語言最困難（包括聽，寫，讀）

寫最難者莫如從右寫向左的阿拉伯文，它的字型结搆有如小蚯蚓般，難怪學阿拉伯文的馬來人(主要用作閱讀阿拉伯文寫的伊斯蘭教可蘭經之用，馬來人都戲稱它為芽菜仔，取其形似之故，隱佔難寫一席者尚有泰文，它雖是由左向右行文但筆劃極怪從上中下前後左右都可寫成字似死蚯蚓，最難學語言當推海南話，它集普通話、閩南話、客家話、壯語(海南主要壯語區)而成，就算在該處住上一輩子也學不會的。

i only talk about the languages I have learnt

german is the most difficult to learn

its nouns has 3 genders: femminine, masculine, neutral (and you can't understand the gender by the ending of the word as in italian or in french)

the adjectives have almost 20 "transformations", depending on the noun and its function in the sentence

greek also is very difficult
