When it comes to expressing time, prepositions play a crucial role in providing clarity and context. Prepositions such as “in,” “on,” “at,” “by,” “before,” “after,” and “during” are commonly used to indicate various aspects of time. Understanding how to use these prepositions correctly is vital for effective communication. In this article, we will delve into the intricacies of using prepositions for expressing time, offering detailed explanations and examples to help you master their usage.
Common Prepositions for Expressing Time
