Etymologically, the entry records: A calque from Ancient Greek κλέπτης ἐν νυκτί (kléptēs en nuktí). 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 thief in the night, spelled T-H-I-E-F- -I-N- -T-H-E- -N-I-G-H-T, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
