It sits outside the most-frequent rank tiers, which is often why uncommon words generate more spelling variants per reader.The dominant gloss from Wiktionary reads: "A regular graph whose spectral gap is almost as large as possible, making it an excellent spectral expander.

Etymologically, the entry records: Named after mathematician Srinivasa Ramanujan. 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 Ramanujan graph, spelled R-A-M-A-N-U-J-A-N- -G-R-A-P-H, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
