Understanding the Phrasal Verb "Brush Up"
Have you ever found yourself struggling to remember a language you studied years ago or feeling a bit rusty when it comes to your piano skills? If so, you likely need to brush up on your abilities. In English, this phrasal verb is a versatile and common expression used to describe the process of reviving or refining knowledge and skills that have gathered a little "dust" over time.
What Does "Brush Up" Really Mean?
At its core, "brush up" implies that you already possess a certain level of knowledge or proficiency, but it has declined due to a lack of practice. It is not usually used for learning something from scratch; rather, it is about returning to a previous level of competence.
- To refresh one's memory: This refers to reviewing facts, information, or languages you once knew well. Example: "I need to brush up on my French before I visit Paris next month."
- To refine or improve: This refers to polishing a specific skill to make it more professional, accurate, or finished. Example: "The coach told the team they need to brush up on their passing techniques before the championship."
Grammar Patterns and Usage
The phrasal verb "brush up" is almost always followed by the preposition "on." When you use it, you generally follow the structure: brush up + on + [noun/skill].
- Brush up on + noun: "I’m going to brush up on my history for the upcoming trivia night."
- Brush up on + gerund (verb + ing): "She spent the weekend brushing up on speaking to clients."
It is important to note that "brush up" is an intransitive phrasal verb in this context, meaning it does not take a direct object like "brush up the history." You must include the word "on" to connect the verb to the subject matter.
Common Mistakes to Avoid
One of the most frequent mistakes learners make is forgetting the preposition "on." Because we "brush" things (like hair or clothes) directly, many people assume they can "brush up" a subject directly. However, in English, the phrasal verb requires the bridge word "on."
Another common error is using "brush up" to describe learning a brand-new skill. If you have never played chess in your life, you should not say you are "brushing up on chess." Instead, you are learning or studying chess. Use "brush up" only when you are revisiting something familiar.
Frequently Asked Questions
Is "brush up" formal or informal?
It is generally considered semi-formal. It is perfectly acceptable to use it in a professional workplace setting—for instance, telling a colleague you are "brushing up on your Excel skills"—but it is relaxed enough to use in casual conversation with friends.
Can I say "brush my skills up"?
You can sometimes separate the phrase, but it sounds more natural to keep the verb and preposition together. For example, "I need to brush up on my skills" flows much better than "I need to brush my skills up."
Is there a difference between "brush up" and "review"?
While they are similar, "brush up" carries the specific connotation of recovering a lost edge. "Reviewing" is a neutral action of looking over information, whereas "brushing up" implies that you have become "rusty" and need to get back to your peak performance level.
Conclusion
The beauty of the English language lies in these descriptive phrasal verbs that capture specific human experiences. Whether you are preparing for a job interview, traveling abroad, or simply trying to get back into a hobby you once loved, remember that it is always a good time to brush up on your interests. By dedicating just a little bit of time to revisit what you already know, you can restore your confidence and sharpen your talents in no time.
