Etymologically, the entry records: From German Arginin, from Ancient Greek ἄργυρος (árguros, “silver”) and ἀργινόεις (arginóeis, “silvery, brightly shining”) in reference to arginine nitrate crystals' silver-white appearance when first refined from lupin seedlings by Ernst Schulze and Ernst … 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 arginine, spelled A-R-G-I-N-I-N-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
