PREPOSITION||Where to use IN,ON, AT|| WITH GREAT EXAMPLES||
Grammar is the foundation for all of our writing and speaking in English. Having a solid foundation makes it easier to achieve fluency. Native speakers can benefit from a refresher on English grammar basics, which they may have forgotten over time. Refreshing the basics is one way to help break bad habits in writing.
English speakers use in to refer to a general, longer period of time, such as months, years, decades, or centuries. For example, we say “in April,” “in 2015” or “in the 21st century.”
Moving to shorter, more specific periods of time, we use on to talk about particular days, dates, and holidays . You may hear, “I went to work on Monday,” or “Let’s have a picnic on Memorial Day.”
For the most specific times, and for holidays without the word “day,” we use at. That means you will hear, “Meet me at midnight,” or “The flowers are in bloom at Easter time.”
This is my wish that I want to see in my all students.
