Oh, seems like no one got my last one – the sha’alah. (I hate dissecting frogs but..) So let try to explain.
The ?????? I’m “klering” about, is called ?????? because that’s what it is. (to put it in delicate terms it would be “output”) The sha’alo would be if it’s considered ????? ?????. Maybe it needs ?????, that’s why all those trucks appear right after Purim.
