Etymologically, the entry records: From being chosen in a competition held among students in the Marianas to name the deep by the discovery team. From association with mythological sirens of the deep. 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 Sirena Deep, spelled S-I-R-E-N-A- -D-E-E-P, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
