Definition

To brush up on something means to refresh, review, or improve one's knowledge, skill, or memory of a particular subject, language, or activity, especially after a period of not having used or practiced it. It implies a focused, often relatively quick, effort to regain proficiency, recall forgotten details, or bring one's competence back up to an acceptable or higher standard. This action is frequently undertaken in preparation for a specific event, test, trip, job, or simply to maintain or enhance one's abilities, rather than starting to learn something entirely new from scratch.
