Relating to the earliest period before or just before birth, an archaic or highly technical term for events immediately preceding nativity.
From 'ante-' (before) + 'natalitial' (an obsolete form relating to birth circumstances). This appears mainly in very old medical and theological texts.
This is a word so obscure it's practically extinct—Victorian doctors used it for the final moments before delivery, but modern medicine simply says 'final labor stage' instead of inventing special terms.
