I think I have mentioned this before, but many decades ago I got one of those Tetrapak containers of milk with the instructions "Lift flap press and tear." It struck me that in the wondrous way of English, almost every word could be a verb, noun or adjective. I imagined a lift/elevator, for example, where the panel in the roof was a flap, and the machine to make it was a press, so that machine was a 'lift flap press'....
