Levantine Arabic doesn't currently have a custom PLURAL function on translatewiki.

Rules:
a. 0: plural

b. 1: its own rule

c. 2: its own rule

d. 3–10: plural

e. 11–102: singular

f. 103–110: plural

g. 111–202: singular

h. 203–210: plural

i. 211–302: singular

…

v. 903–910: plural

w. 911–1,002: singular

And it keeps on going in the same pattern.
