Understanding the Phrasal Verb: Speed Up
Whether you are learning English for business, travel, or academic purposes, phrasal verbs are an essential part of sounding fluent. One of the most useful and versatile phrasal verbs you will encounter is speed up. It is a simple term that describes the act of increasing pace or velocity. By mastering how to speed up your speech and writing, you can express yourself more clearly and dynamically.
What Does "Speed Up" Mean?
At its core, to speed up means to increase the rate of movement or the pace at which a process occurs. Depending on the context, it functions as both an intransitive verb (happening on its own) and a transitive verb (done to something else).
1. To move faster
When you are walking, driving, or running, you can speed up to reach your destination sooner. In this sense, the subject of the sentence is the one increasing their own movement.
- The driver had to speed up to pass the slow truck in front of us.
- If we don't speed up, we are going to miss the start of the movie.
2. To cause something to happen more quickly
You can also use this phrase to talk about processes, projects, or growth. If something is taking too long, you might look for ways to speed up the timeline.
- Drinking coffee in the morning helps speed up my metabolism.
- The new software update will speed up your computer’s performance significantly.
Grammar Patterns and Usage
The beauty of speed up is that its grammatical structure is straightforward. As a phrasal verb, it acts as a single unit of meaning. Here are the common ways to structure your sentences:
- Intransitive usage: No object is needed. "Please speed up!"
- Transitive usage: You can place an object after the verb. "The manager wants to speed up the hiring process."
- Separable rule: This phrasal verb is separable. You can put the object between "speed" and "up" if it is a pronoun, though it is more common to keep the phrase together. For example: "We need to speed the project up" is correct, but "We need to speed up the project" is more common.
Common Mistakes to Avoid
Even advanced learners sometimes stumble when using speed up. Keep these tips in mind:
Confusing it with "hurry up": While hurry up is often used for people (e.g., "Hurry up and get dressed!"), speed up is more often used for machines, vehicles, or long-term processes. Using speed up to tell a friend to hurry is technically correct, but it can sound slightly mechanical.
Past tense errors: Remember that since "speed" is the verb, the past tense is sped up (or sometimes speeded up, though sped up is much more common in modern English).
