Etymologically, the entry records: It was reported independently in 1884 by German chemists Carl Paal and Ludwig Knorr. 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 Paal-Knorr synthesis, spelled P-A-A-L---K-N-O-R-R- -S-Y-N-T-H-E-S-I-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
