## Definition

connected to the sac of fluid that protects a baby inside its mother before birth. Doctors check this fluid and sac to see if the pregnancy is healthy.

For teachers: relating to the amnion or the fluid-filled sac surrounding a fetus in the uterus. Commonly collocates with 'fluid', 'sac', and 'membrane' in obstetric contexts.

## Examples

- The doctor checks the amniotic fluid during pregnancy.
- During the ultrasound, the doctor measures the amniotic fluid to make sure the baby has enough protection.
- A rupture of the amniotic sac before labour begins often prompts close monitoring, since the protective fluid cushions the fetus and guards against infection.

## Usage notes

- Typically placed before the noun it modifies.
