Etymologically, the entry records: Onomatopoeic, perhaps borrowed; compare German bummen, Dutch bommen (“to hum, buzz”). The sense "a period of economic growth" is generally taken to derive from the sense "a rapid expansion", although other origins have also been suggested. 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 boom, spelled B-O-O-M, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
