English prepositions: choose natural words for relationships
A meeting can start at nine, happen on Tuesday, and take place in a small room. The event is the same, but each relationship needs a different preposition.
Choose a common preposition by identifying the relationship between the words around it.

The short answer
Choose a preposition from the relationship in the sentence. Use at for a point, in for an enclosed space or longer period, on for a surface or day, by for a method or deadline, for for purpose or duration, and with for company or a tool.
The report is on the desk beside the window.
Why it works: On describes the report's position on a surface.

Do not try to learn every preposition as a separate translation. Start by asking a practical question: What is the relationship here? Is something located at a point, inside a place, on a surface, moving to a destination, done with a tool, or happening for a reason? That question gives you a smaller set of likely choices.
Find the relationship before the word
Prepositions become easier when you identify what they connect. In The keys are on the table, the relationship is position on a surface. In We arrived at noon, the relationship is a precise time. The noun after the preposition matters, but the intended relationship matters more.
The museum is near the river.
Near describes distance. At the river would treat the river as a particular point or location.
A bus reaches a precise stop. Which short word commonly introduces that stop?
Use at: The bus stopped at the corner.
Use at, in, and on for place and time
At often marks a point: at the door, at the traffic lights, at 8.15. In often marks a larger place or a longer time period: in the kitchen, in Kenya, in October, in 2027. On often marks a surface or a named day: on the wall, on Monday, on my screen.
The workshop begins at ten on Wednesday in Room 4.
At ten is a clock time, on Wednesday is a day, and in Room 4 is an enclosed location.
A place can take different prepositions when the viewpoint changes. Meet me at the airport treats the airport as a point. Wait for me in the airport means inside the building.
Separate destination from method
Use to for a destination and by for a method. They can occur in the same sentence because they answer different questions: Where is something going? How will it travel?
I sent the photos to my aunt by post.
To my aunt names the recipient. By post names the sending method.
The team travelled to Leeds by coach.
Which word names the method in She paid ___ card?
Use by: She paid by card.
Use for and with to add purpose and company
For can show why an action happens, who receives something, or how long something lasts. With can show the person who joins an activity or the thing used to perform it.
I bought a notebook for my course.
I revised with my cousin after dinner.
For my course gives the notebook's purpose. With my cousin tells us who joined the revision.
Compare I cut the paper with a knife and I cut the paper for an art project. The first phrase gives the tool. The second gives the purpose.
Learn useful adjective and verb patterns as units
Some prepositions are strongly linked to a nearby adjective or verb. Learn the whole phrase: depend on, listen to, wait for, interested in, worried about, and responsible for. A grammar rule may help, but a remembered phrase often helps you speak faster and more naturally.
The final decision depends on the weather.
Lina is interested in local history.
Depends on connects a decision to what controls it. Interested in connects a person to a topic that holds their attention.
Which preposition completes They are responsible ___ checking the equipment?
Use for: They are responsible for checking the equipment.
Before you go
Remember this
Choose prepositions from relationships. At marks a point, in marks an area or longer period, on marks a surface or day, by can name a method or deadline, for can show purpose or duration, and with can name a companion or tool. Build a phrase around the word instead of memorising an isolated translation.

How do I choose between at, in, and on?
Choose the word from the relationship. Use at for a point such as a meeting place or clock time, in for an area, enclosed space, month, or year, and on for a surface or named day. Compare meeting at the library entrance with spending the afternoon in the library.
Maya will meet us at the library entrance at half past four.
Why can the same place use different prepositions?
The viewpoint can change. At the library treats it as a point where people meet, while in the library means inside the building. The noun has not changed; the relationship has.
Maya spent the afternoon in the library.
What is the difference between by and to?
To usually names a destination or recipient, while by can name a method. In send the form to the admissions office by email, to tells us where the form goes and by tells us how it is sent.
The children drew maps on large sheets of paper.
When do I use for and with?
Use for for a purpose, recipient, or duration, and use with for company or a tool. A stay can last for three nights, and a person can open a parcel with scissors.
The children kept the maps in a blue folder.
Should I memorise prepositions one by one?
Learn common patterns as short phrases as well as broad relationships. Phrases such as depend on, interested in, and responsible for are easier to use when you remember the nearby word with its usual preposition.
