Etymologically, the entry records: Genericized trademark, from "NIX I", abbreviation of "Numeric Indicator Experimental No. 1" with diminutive -ie. 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 Nixie tube, spelled N-I-X-I-E- -T-U-B-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
