No explicit etymology string is stored for this entry, so spelling patterns must be inferred from the word's phoneme-to-grapheme mapping rather than from a documented borrowing chain. For readers arriving here from a spelling check, the authoritative guidance is: the correct French form is nombre de Fibonacci, spelled N-O-M-B-R-E- -D-E- -F-I-B-O-N-A-C-C-I, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
