Oh my cousin May Allah bless your life-time it is عمركِ in its root version, but we have started to use the sound "ch" instead of "k" when talk to female , this is taking from the effect of turky and persian langauge in the arabic dialect, in Iraq and some guld countries we can pronounce clear "ch" sound for some egyption-like dialects who cannot say it as "ch" they pronounce it as "sh" sound

god bless your age,cousin اللة يبارك في عمرك يا بنت عمي

God bless your age, cuzin
