Etymologically, the entry records: From sleep + deprived. 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 sleep-deprived, spelled S-L-E-E-P---D-E-P-R-I-V-E-D, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
