Etymology

Origin of coalition

1605–15; < Latin coalitiōn- (stem of coalitiō ), equivalent to coalit ( us ), past participle of coalēscere ( co- co- + ali-, past participle stem of alere to nourish + -tus past participle suffix) + -iōn- -ion; coalesce

Explanation

A coalition is a group of people who join together for a common cause, like a coalition you form with other skateboarders who want to convince your town to build a skate park. The noun coalition comes from the Latin word coalitiō, meaning "to grow together." Often, the people and groups that form coalitions have different backgrounds but come together because they share a goal. For example, parents, teachers, business owners, and city council members might form a coalition to build a teen center, just as nations that do not agree on all issues might form a coalition because they all want peace.
