Understanding the Phrasal Verb "Block Out"
The English language is filled with phrasal verbs that change their meaning depending on the context, and block out is a perfect example of this versatility. Whether you are trying to keep the bright sun from waking you up on a Saturday morning or sketching the initial timeline for a complex project, understanding how to use this phrase will help you communicate more precisely. Let’s dive into the different ways we use block out in everyday English.
Core Meanings and Usage
The phrasal verb block out is generally used to describe the act of stopping something from passing through, or alternatively, the act of creating a rough plan for something. Here are the primary ways native speakers use it:
1. To stop light or sound from entering
This is perhaps the most common way to hear the term. When something creates a barrier, it effectively keeps unwanted sensory input away.
- Heavy curtains are perfect if you want to block out the strong sunlight in the morning.
- I wear noise-canceling headphones to block out the sound of the traffic while I work.
2. To ignore or suppress thoughts
In a metaphorical sense, we use block out when we want to stop thinking about a painful memory or a distraction.
- He tried to block out the negative comments and focus on his performance.
- It is hard to block out the stress of the day when you finally get home.
3. To draft or outline (planning)
In professional or creative settings, block out means to plan the general structure or placement of something, often before adding the fine details.
- The director spent the afternoon trying to block out the scenes for the new musical.
- I usually block out my calendar for the week on Sunday nights so I know exactly when my meetings are.
Grammar Patterns
The phrase block out is a transitive phrasal verb. This means it almost always requires an object—you are usually blocking out something. Because it is separable, you can place the object between the verb and the preposition, though keeping them together is also perfectly acceptable.
- Separable: "She blocked the sun out with her hand."
- Together: "She blocked out the sun with her hand."
Common Mistakes
One common mistake learners make is confusing block out with block up. While block out usually refers to light, sound, or abstract plans, block up is typically used for physical obstructions in narrow spaces, such as "blocking up a sink" or "blocking up a pipe." Avoid using them interchangeably.
Another point of confusion is thinking that block out always means to physically stop something. Remember that in the context of scheduling, it is purely about time management. If you tell a colleague, "I've blocked out some time for that project," you haven't stopped the project—you have simply reserved a space for it on your schedule.
Frequently Asked Questions
Is "block out" formal or informal?
It is neutral and suitable for almost any context, from casual conversation to professional emails about scheduling.
Can I use "block out" for physical objects?
Generally, no. We use it for light, sound, mental images, or time. If you want to say that a large object is stopping you from seeing something, it is more natural to say "The building is blocking my view."
What is the difference between "block" and "block out"?
"Block" is a simple verb that means to obstruct. "Block out" adds the nuance of excluding something entirely from your awareness or from a space (like light through a window).
