What is the action of growing together or merging called?

The term "coalesce" refers to the process of growing together or merging into a single entity. It is commonly used in various contexts, such as in biology to describe how different cells or tissues can combine, or in social sciences to illustrate how groups or ideas can come together to form a unified whole. The fundamental aspect of coalescence is the idea of disparate elements combining, which resonates with the concept of synergy, where the outcome is greater than the sum of its parts. Thus, in scenarios where merging or integration is emphasized, "coalesce" is the appropriate term to describe that action.
