My new bumper sticker

I was walking home the other day when a car passed me with a bumper sticker like this: אני דובר ארמית — I Speak Aramaic. He pulled in and parked ahead of me so I waited for him to get out and said politely צַפְרָא טָבָא, and told him that I liked the sticker, and where could I get one? He immediately pulled two more out of the car and presented them to me.

We spoke for a few minutes, and it turns out that he is a native Aramaic speaker, and that the stickers are put out by an organization that has just opened an office in the centre of Jerusalem (in Ben Yehuda Street, appropriately enough), and they are planning to start holding classes in spoken Aramaic.

My only question is, why doesn’t it say אנא מליל ארמיא?
