Arabic is pretty better than French and German in such stuff. Very reasonable language with not much exceptions. Laters you will study how the gender of nouns and their role in in the sentence affect the whole sentence. When you comparison it with a latin or germanic language, u will see how meaningful and reasonable are those affections and how they make arabic so precise.
Firstly, in Arabic (like in many other languages like French and Indonesian) the adjective comes AFTER the noun it is describing. So in Arabic you say jacket new, television big, hair beautiful in stead of new jacket, big television and beautiful hair.
Secondly, in Arabic there is the ال al-, making words definite. If a word does not have the definite article, then it is indefinite (the English equivalent of 'a' or 'an').
The big book= al-kitaab al-kabiir.
A big book= kitaab kabiir
The book is big= al kitaab kabiir
