Understanding Prepositions of Time
Prepositions of time are words that help us talk about when something happens. They are small words like at, on, and in that give us important information about time.
Basic Structure
Prepositions of time are used before a time expression. They usually come before nouns or pronouns to show the time of an action.
How Prepositions of Time Work
- At is used for precise times. For example, "at 3 o'clock" or "at noon".
- On is used for days and dates. For example, "on Monday" or "on July 4th".
- In is used for longer periods like months, years, centuries, and long periods. For example, "in April", "in 2023", or "in the morning".
