Etymologically, the entry records: First noted by Gustav Spörer in publications in 1887 and 1889, work that was relayed to the Royal Astronomical Society in London, and then expanded on, by the solar astronomers Edward Walter Maunder (1851–1928) and (his wife) Annie S. D. Maunder (1868–1947). Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is Maunder Minimum, spelled M-A-U-N-D-E-R- -M-I-N-I-M-U-M, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
