What does suptitle really mean in matplotlib?

Question

In using any package, the name of a function should be obvious so that our brain does not keep remembering weird features.

So in matplotlib, every time I use suptitle, I have no idea what "sup" is for. Does anyone have this problem or do we just use it since the standard said so?

Answer 1

"Super title" is the official meaning. This has been confirmed by the matplotlib devs:

suptitle stands for super title. The word super comes from the latin language, meaning "above." A suptitle is hence a title that stands above the axes of the figure, on top of it. This is in contrast to a normal title which is bound to an axes.
