Premature means happening too early, before the right or expected time. When something is premature, it arrives or occurs before it's fully ready or before conditions are right for it.

The word comes up often in medicine. A premature baby is born weeks before the expected due date, sometimes needing special care because its body hasn't finished developing. Doctors and nurses work carefully with premature infants to help them grow stronger.

But premature describes many situations beyond medicine. A premature celebration happens when someone starts cheering before they've actually won. Imagine celebrating victory in a basketball game when you're ahead by two points with three minutes left to play: the other team might still catch up, making your celebration premature. A premature conclusion means deciding something before you have all the facts, like assuming your friend is angry at you before asking what's actually wrong.

The opposite of premature is mature or timely. Something premature lacks the benefit of proper timing. It's like opening your birthday presents a week early or harvesting fruit before it's ripe. Sometimes being premature just means inconvenient timing, but it can also mean missing out on something important that would have happened if you'd waited.
