Definition

At this and in this are both phrases used to refer to a specific point in time or a specific location. However, they are used in slightly different contexts and have different nuances in meaning.

Usage

The phrase "at this" is typically used to refer to a specific point in time. For example, "I will be ready to leave at this time." On the other hand, "in this" is used to refer to a specific location or situation. For example, "I found this book in this room."

Time vs. Location

One of the key differences between "at this" and "in this" is that the former is used to refer to time, while the latter is used to refer to location. This distinction is important to keep in mind when deciding which phrase to use in a sentence.

Specificity

Another difference between the two phrases is the level of specificity they convey. "At this" is often used to pinpoint a specific moment in time, while "in this" is used to describe a more general location or situation. For example, "I will meet you at this time" is more specific than "I will meet you in this place."

Context

Context plays a crucial role in determining whether to use "at this" or "in this" in a sentence. Consider the context in which the phrase is being used and choose the one that best fits the situation. For example, if you are talking about a specific time, use "at this." If you are referring to a specific location, use "in this."

Examples

• "I will be ready to leave at this time." (using "at this" to refer to a specific point in time)
• "I found this book in this room." (using "in this" to refer to a specific location)
• "Let's meet at this restaurant for dinner." (using "at this" to refer to a specific location)
• "I will call you at this hour." (using "at this" to refer to a specific point in time)

Conclusion

While "at this" and "in this" may seem similar at first glance, they have distinct differences in meaning and usage. Understanding these differences can help you choose the right phrase for your sentence and communicate more effectively. Pay attention to the context, whether you are referring to time or location, and the level of specificity you want to convey when deciding between "at this" and "in this."
