Pane

Pane

Noun · /peɪn/ · a single sheet of glass in a window or door

Definition

A single flat piece of glass set within a frame — typically one section of a window or door. Also used in computing for a distinct rectangular region within a user interface: a split pane, a side pane, a navigation pane.

Origin

From Old French pan, meaning a section or panel, from Latin pannus, meaning a piece of cloth or section. The idea of a flat, bounded section travelled from fabric to architecture to glass over the centuries.
