This lesson explains how to use the prepositions to, in and at for place, movement and time. These three short words often cause confusion because their meanings change with context. Knowing the main uses will help you choose the correct preposition in business and everyday situations.
'to' usually shows movement toward a destination or a limit in time.
'in' is used for enclosed spaces, larger areas, and periods of time (months, years, seasons).
'at' is used for specific points in space or time (points, addresses, clock times, events).

Example
to
Movement toward a destination; limit in time (from...to...)
She walked to the office.
in
Enclosed spaces, cities/areas, and longer time periods (months, years, seasons, parts of day)
He works in London. / The report is due in June.
at
Specific points, addresses, events, clock times
Meet me at the reception. / The meeting starts at 9:00.
Tip
Key rule: Place and time guide your choice
Use the general spatial/time idea to pick a preposition:
For movement toward a destination use 'to' — verbs like go, travel, send: We are going to the client site.
For location inside an area or during longer periods use 'in' — parts of cities, countries, months, years: The office is in the business district.
For specific points in space or time use 'at' — particular places, addresses, events, clock times: The interview is at 10:30.
Think: to = movement, in = inside/period, at = specific point
Example
Examples in context
The consultant flew to Madrid for the client meeting.
Our team works in the new office building on 5th Avenue.
Please arrive at the reception desk at 8:45 AM.
The contract is valid from January to December.
Tip
Common mistakes to avoid
Learners often confuse these prepositions. Watch for these universal errors:
Using 'in' for a specific clock time (wrong: in 3 PM → correct: at 3 PM).
Using 'at' for large areas or countries (wrong: at France → correct: in France).
Using 'to' instead of 'at'/'in' after verbs of position (wrong: I am to the office → I am in/at the office).
Omitting the preposition entirely in phrases that require one (wrong: arrive the office → arrive at the office).
Mixing up 'to' as a preposition of movement with 'to' that starts an infinitive (watch the verb structure).
When in doubt, ask: Is this movement, an enclosed area/period, or a specific point?
