No misspelling variants are generated for calthemite in our index, suggesting the orthography follows predictable English patterns. It is not paired with a close-neighbour confusable in our dataset, which tends to mean the word is visually distinctive enough to stand on its own.

Etymologically, the entry records: From Latin calx (“lime”) + Latin < Ancient Greek θέμα (théma, “what is laid down”), (also Mediaeval Latin thema, "deposit") and the Latin -īta < Ancient Greek -ίτης (-ítēs) – used as a suffix indicating a rock or mineral. 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 calthemite, spelled C-A-L-T-H-E-M-I-T-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
