Donny, I don’t speak French and I don’t speak Portuguese; I can tell you that the article in Arabic is the easiest thing in the world; there is only one, and it is “al”= the
The hard thing in Arabic is that every person/gender/number must match, and sometimes that matching involves intentional mismatching.
If you want to say “four girls” you must say “3rba3 banat”, which is the masculine singular word for ‘four’ and the feminine plural word for “girls”.
If you pass the number ten, things get trickier. If you want to say “fifteen girls” you must say “khamsata 3ashara bint”, which means, “the feminine form of fifteen, which, being a number, is hard to say whether it is plural or singular”, then, you must say “girl” which is the singular form of the word girl; I did not accidentally leave off the s. The second word would also have to be in the genitive case, incidentally, which is because it is considered a “tamyeez” ie, a comparison. The word would end like this, “bintin”
