Okay, sweetie, let me tell you about Cenchrea. Cenchrea is a special place mentioned in the Bible. It's spelled with a "C" and then an "E" with a squiggly line, like this: Cenchreae. It's actually a port city in Greece!
Now, a port city is a place where boats come and go. It's like a big parking lot but for boats! They park their boats there and get supplies or go shopping or visit friends. Some people who live near the port city might work there, helping to load and unload the boats or sell things to the people on the boats.
Saint Paul, who was a really important person in the Bible, visited Cenchrea when he was traveling around to tell people about Jesus. He met some nice people there and they helped him with his journey. That's why Cenchrea is special to some people who follow the Bible.
So that's what Cenchrea is, sweetie: a port city in Greece that Saint Paul visited a long time ago.
