“pain” vs. “pane”
Write "pain" for physical or emotional suffering (noun or verb); write "pane" only for a sheet of glass in a window or door.
pain
"Pain" is a noun and verb describing physical or emotional suffering ("she felt a sharp pain"; "it pains me to say this"). It comes from Latin "poena" (penalty, punishment), through Old French "peine," reflecting an older worldview in which suffering was closely tied to the idea of punishment or retribution, a connection that has faded from the modern, purely physical or emotional sense of the word.
pane
"Pane" is a noun naming a single sheet of glass, especially one fitted into a window or door frame ("a broken window pane"). It comes from Old French "pan" (a section, a piece, a side of something), related to Latin "pannus" (a piece of cloth), since the word originally described any distinct section or piece of a larger structure before narrowing specifically to glass window sections.
The real distinction
"Pain" and "pane" are homophones with entirely separate roots, one tracing back to a Latin word for punishment, the other to a Latin word for a piece or section of cloth, converging only by coincidence on identical modern pronunciation. The words are easy to sort by topic and grammar together: "pain" functions as a noun describing suffering (physical or emotional) or as a verb meaning to cause distress ("it pains me"), appearing constantly across medical, emotional, and everyday conversational writing. "Pane," by contrast, is always a concrete noun naming a section of glass, almost always appearing alongside "window," "glass," or a description of a frame ("a cracked pane," "the window's four panes"). If the sentence describes suffering, discomfort, or distress, you want "pain"; if the sentence describes a section of window glass, you want "pane." A useful confirmation: "pane" is always countable and nearly always modified by "window" or a number describing how many sections a window has ("a six-pane window"), a pattern "pain" never follows, since pain is typically treated as an uncountable noun describing a general sensation rather than a discrete, countable object. Stained-glass windows historically used the word 'pane' to describe each individual colored glass section within the larger design, a usage still current in writing about church architecture and historic preservation, distinct from the plain clear panes found in ordinary home windows. Medical writing distinguishes between many specific types of pain — acute, chronic, referred, phantom — each describing a different clinical pattern of suffering, a level of specialized vocabulary that has no equivalent for 'pane,' which instead appears in a much narrower range of contexts centered on windows, doors, and glass construction. Historic preservation writing about old buildings sometimes specifically counts window panes as a way of dating or identifying a structure's original construction period, since the number and size of panes in a window often reflects the glassmaking technology available when the building was built.

Memory trick
Link "pain" to "penalty," its distant Latin relative, both carrying an old sense of suffering or punishment. Link "pane" to "pattern" or "panel," words describing distinct sections of something larger, matching the way a windowpane is one section within a larger window frame.
