Pregnant means carrying a developing baby inside the body. When a woman is pregnant, a baby grows inside a special organ called the uterus for about nine months before being born. During this time, the mother's body changes to support the growing baby: she might feel tired, her belly grows larger, and she needs extra nutrition and rest.

Doctors and nurses monitor pregnant women to make sure both mother and baby stay healthy. Pregnancy is a natural process that happens in humans and most mammals. A cat can be pregnant with kittens, a dog with puppies, and a horse with a foal.

The word can also describe something full of meaning or possibility. A pregnant pause in conversation is a meaningful silence where something important hangs in the air, waiting to be said or understood. A pregnant moment in history is one loaded with significance, like when scientists are about to announce a major discovery. In this sense, pregnant suggests something heavy with potential, ready to bring forth something new and important.
