Definition

To accumulate means to gather or build up something gradually over time.

To accumulate is to collect or increase something little by little until there is a larger amount. It often describes money, objects, evidence, or effects that grow through repeated additions. The focus is on a gradual process rather than a single sudden change.

Examples

Common mistake
