Issue with Arabic Plural Categories in Translation

[nadabou]

Hello Team,

While testing the Arabic translation feature, I noticed that the current handling of plural categories may not align with Arabic grammar rules.

Based on my understanding as a native speaker, I suggest the following logic:

0 → plural
1 → singular
2 → dual
3–10 → plural
11+ → singular (used in a specific grammatical structure)
I checked the Unicode documentation but couldn’t find clear guidance, so I’m sharing this reference instead:
👉 The Grammar of Using Arabic Numbers – The Arabic Pages

Here’s a simple JS function reflecting this logic:

function getArabicPluralForm(n) {
if (n === 0) return "plural";
if (n === 1) return "singular";
if (n === 2) return "dual";
if (n >= 3 && n <= 10) return "plural";
if (n >= 11) return "singular";
}
Could you please verify if this logic is correct from your side or let me know if there's another standard being followed?

Thank you!
