Could somebody tell me what neonatal death means (especially what neonatal means) please

Neonatal refers to a newborn baby. Specifically the first four weeks of a baby's life. So, a neonatal death is when a baby dies within the first month of birth/life.

Thank you

Neo is Latin for new

Natal is Latin for baby

And thank you

Actually 'natal' means 'birth' not baby.
