Other forms: panes
A pane is one single sheet of glass in a window. A broken pane, double-glazed pane, replace the pane.
Older windows are made of many small panes because large sheets of glass were hard to make; modern ones are one or two large panes with gas between them. In software a pane is a division of a window, borrowed from exactly this image. Note that the word comes from the Latin for a cloth, oddly, through French.
