Shouldn't it be pictures of a warehouse first, and then on the full moon it turns into a house making it a werehouse? A werewolf turns into a wolf on the full moon, so the "were" prefix should proceed what it turns into. Unless this is supposed to be a were-warehouse.
A werewolf is always a werewolf that transforms from man (prey) to wolf (predator) when there is a full moon. So in this example the werehouse would go from house to wrecking ball.
kinda, the "were" actually comes from old Germanic "wer", meaning "man". Werewolf just means "man wolf" lol. So I suppose a warehouse could be a human who turns into a house at full moon
