Each preposition has specific rules governing its usage, which we will explore in detail.

Common Mistakes and How to Avoid Them
Understanding the rules is one thing, but applying them correctly is another. Here are some common mistakes learners make and tips to avoid them:
Confusing ‘in’ and ‘on’
Learners often mix up in and on when referring to dates and parts of the day.
Incorrect: She was born in January 5th.
Correct: She was born on January 5th.
Tip: Use in for months and on for specific dates.
Using ‘at’ instead of ‘in’ or ‘on’
Another common error is using at instead of in or on.
Incorrect: I will see you at the evening.
Correct: I will see you in the evening.
Tip: Remember that at is for precise times, in is for parts of the day, months, years, and centuries, and on is for days and dates.
Misusing ‘since’ and ‘for’
Learners also frequently confuse since and for.
Incorrect: I have lived here for 2010.
Correct: I have lived here since 2010.
Tip: Use for to indicate duration and since to indicate the starting point of an action that continues to the present.
Overusing ‘during’
The preposition during is sometimes overused when another preposition would be more appropriate.
Incorrect: We stayed at the hotel during a week.
Correct: We stayed at the hotel for a week.
Tip: Use during for specific periods or events, and for for durations.

Advanced Usage and Nuances
As you become more comfortable with basic prepositions of time, it’s important to understand some of the more advanced usages and nuances.
‘Within’ vs. ‘In’
While in refers to a general period, within specifies a limit.
Examples:

– The package will arrive within a week (implying it could arrive any time before the week is up).
‘By’ vs. ‘Until’
Both by and until can refer to deadlines, but by implies a one-time action, while until suggests a continuous action up to the deadline.
Examples:
– Please finish the report by Friday (a one-time action).
– You can stay here until Friday (a continuous action).
‘Throughout’
The preposition throughout is used to indicate something happening continuously over a period.
Examples:

‘From…to/till/until’
These combinations are used to indicate the start and end points of a period.
Examples:
