Born dead; stillborn or delivered without any signs of life.
Compound word from 'dead' (not alive) and 'born' (delivered from the womb). The term has been used since medieval times to describe infants born without vital signs.
Before modern medicine, deadborn infants were so common that they were documented separately from living children in records—thankfully, prenatal care and medical technology have reduced stillbirth rates by over 50% in developed countries in recent decades.
