late 19th century: from Greek hupnos ‘sleep’ + -osis.
wiktionary
Derived from hypn(otic) + -osis(“state”, “condition”, nominal derivational suffix).
etymonline
hypnosis (n.)
1850, "the coming on of sleep," coined (as an alternative to hypnotism) from hypno- "sleep" + -osis "condition." But the distinction was not sustained, and by 1876 hypnosis was being used of artificially induced conditions.
