I have deduced the plural forms for ngettext
Plural-Forms: nplurals=2; plural=(n>9)?(n % 100 >2 && n % 100 < 11):(n % 10 >2)
to be used with
char * ngettext (const char *MSGID1, const char *MSGID2,unsigned long int N)
the translation of MSGID1 is singular and MSGID2 is plural, no MUTHANNA is needed
because we don't say 2 namlatan, NASKH 2 MALAFFAN
this note is importent for translators
