The phrasal verb "work up" is predominantly used in informal speech and writing. It is versatile, appearing in several contexts with different meanings. Commonly, "work up" is used to mean developing or building up something, often gradually, such as emotions (e.g., "he worked up the courage to speak") or skills (e.g., "working up the ranks"). Additionally, it can refer to stimulating or energizing oneself (e.g., "to work up an appetite"). Another usage involves escalating emotions or tensions, such as "getting worked up" about a particular issue. While "work up" can occasionally appear in more formal contexts, alternative phrasing is usually preferred in professional or academic settings. Its informal nature lends itself well to conversational English, making it a common choice for everyday exchanges.
