The phrase coalesce definition refers to the meaning of the verb coalesce, which generally means to come together to form one mass or whole.
Used literally, it can describe droplets of oil joining into a single bead, or islands of agreement on a committee gathering into a policy. Used figuratively, it describes ideas, groups, or forces that merge into something larger.
Etymology and Origin of coalesce definition
Tracing the coalesce definition back in time shows Latin roots. The English verb comes from Latin coalescere, composed of co, meaning together, and alescere, meaning to grow up or to nourish.

In politics and social commentary, coalesce describes coalitions forming from varied interests. It suggests not just mixing, but an organized, sometimes emergent union.
