Well said: ''the limit of my language, is the limit of my world''. I add , and the limit of my imagination and thinking. As an Iranian , the Arabic grammar was in our study curriculum. Arabic is easy language: once we learn one root word and learn the inflection rule , we know 16 words. Example: root word KTB then Ketab= book Mokatebeh= writing Maktab= place reading book and so on. Plus , Arabic is very rich in vocabulary. Arabic was a developed language 1400 years ago, and we owe it to Yemen civilization, ( in my opinion the mother of entire west Asian civilization). What was the status of English, and German language 1,400 years ago?
The earliest attested arabic is from 853BC so 3000ish years ago and not 1400 years ago. Absolutely no linguist will agree with the "Arabic is from Yemen" thing either which goes against all philological evidence. If you don't know what you're talking about (which you obviously don't given that you don't know shit about Semitic philology) please don't spread random disinformation.
