Definition: The word 'accumulate' means to accumulate or to accumulate something over time or in a particular way. It can also mean to build up, develop, or progress. In general, the use of "accumulate" is usually directed towards an action that involves increasing quantities or amounts by repeatedly performing some kind of operation or process. For example: - In mathematics, if we say something like "The sum of 3 numbers added together is 12", it means to accumulate the numbers into a total of 15, as 3 + 4 + 5 equals 12. - The word "accumulate" can also be used in the context of science or engineering terms, such as the process of accumulation where materials are moved from one location to another. Overall, the word 'accumulate' is typically used when describing an action that requires increasing quantities over time or a method for developing or growing something.
