Coalesce means to come together and unite into a single whole. When separate things coalesce, they merge or combine to form something unified and complete.

Imagine a group project where everyone starts with different ideas scattered across the table. As you discuss and refine, those separate thoughts begin to coalesce into one clear plan everyone can work on together. Or picture tiny water droplets on a window: at first they're separate beads, but as more moisture collects, they coalesce into larger drops that roll down the glass.

The word often describes gradual processes rather than sudden combinations. After a big argument, a family's feelings might slowly coalesce into forgiveness and understanding. In history, separate colonies coalesced to form the United States. Scientists watch as dust and gas in space coalesce over millions of years to form new planets.

Coalesce suggests that the separate parts truly blend into something new. When your class brainstorms ideas and they finally coalesce into a workable solution, you've created something unified that everyone can support.
