Understanding the Basics of Prepositions
Prepositions are words that link nouns, pronouns, or phrases to other words within a sentence. They provide essential information about time, place, direction, and manner. "In" and "on" are two of the most frequently used prepositions in English, and mastering their usage is crucial for effective communication.

- The cat is in the box.
- She lives in New York City.
- The cookies are in the oven.
2. Referring to Time Periods
"In" is also used to denote time periods, particularly months, years, and long durations. Consider the following examples:
