Prepositions of Time
"Small words like 'in', 'on', and 'at' make a big difference when talking about your schedule."
In, On, and At
Learn how to connect activities to specific times.
When we talk about our daily routine, we need short connecting words called prepositions. The three most common prepositions of time are in, on, and at.
Use "in" for longer periods or parts of the day. For example, you eat breakfast in the morning, work in the afternoon, and relax in the evening.
Use "on" for specific days and dates. If you work hard on a weekday like Monday, you can enjoy your free time on the weekend.
Finally, use "at" for exact clock times and certain exceptions. You arrive at 8:00 AM, go to your appointment at 2:30 PM, and go to sleep at night.
