Examples:

“While choosing a single film to encapsulate a quarter-century of cinema is an impossible task, Bong Joon Ho’s dark comedy certainly belongs in the conversation. A scathing satire that links two families of vastly different means, the film’s stars thinly smile through the indignities and social faux pas before a climactic and inevitable eruption of violence.” — Kevin Slane, Boston.com, 2 Jan. 2026

Did you know?

We’ll keep it brief by encapsulating the history of this word in just a few sentences. Encapsulate and its related noun, capsule, come to English (via French) from capsula, a diminutive form of the Latin noun capsa, meaning “box.” (Capsa also gave English the word case as it refers to a container or box—not to be confused with the case in “just in case,” which is a separate case.) The earliest examples of encapsulate are for its literal use, “to enclose something in a capsule,” and they date to the late 19th century. Its extended meaning, “to give a summary or synopsis of something,” plays on the notion of a capsule being something compact, self-contained, and often easily digestible.
