Understanding Prepositions Through Context

This is a supplimental reading for an assignment given to help CELPIP students with prepositions. Prepositions are often difficult for new English speakers. For the CELPIP using the correct prepositions for speaking and writing are essential to get a high score. This is part of an entire Canadianization course being offered to people who are new to Canada and trying to get permanent residence. Assimilation into certain parts of Canadian life can be difficult and it is a must if P.R. candidates want to be successful and have a balanced, low stress life. Unfortunately most of the formatting has been lost in order to publish to Vocal.

A preposition is a word that shows the relationship between a noun (or pronoun) and other words in a sentence. It helps give crucial context to define a sentence's meaning, typically referencing time, place, direction, or spatial location.

How you choose your preposition changes the physical or logical reality of the sentence.

Example: "The Front Yard"

• My friend is in the front yard.
• Your friend is on the front yard.
• They put stone over the front yard.
• There are ants under the front yard.
• Behind the front yard is a garden.
• The front yard is in front of the house.
• The path cuts through the front yard.
• The front yard is between the sidewalk and the garden.
• The grass is planted after the front yard is level.
• The fence posts should be set before the front yard is leveled.
• The fence will go around the front yard.

In the example block above, all of the sentences are valid in their own way. However if the preposition is used incorrectly the sentence itself can become incorrect. You wouldn't say 'My friend is on the front yard.' if your friend was standing on the walkway. The walkway may be in the front yard area but your friend is specifically on the walkway as an object.

Detailed Breakdown: When and Why to Use Each Preposition

To understand how these prepositions change the meaning of the sentence, we have to look at the specific spatial and temporal (time) rules for each one.

1. "in" (My friend is in the front yard.)

Why it is used: "In" is used for enclosed spaces or areas with defined boundaries (even invisible ones, like a property line).

When to use it: Use "in" when the subject is physically located inside the perimeter of an area (e.g., in the park, in the yard, in a room).

2. "on" (Your friend is on the front yard.)

Why it is used: "On" denotes physical contact with a surface.

When to use it: Use "on" when you want to emphasize that the subject is directly touching or standing on top of the physical ground, grass, or dirt (e.g., on the lawn, on the floor).

3. "over" (They put stone over the front yard.)

Why it is used: "Over" is used when one thing covers, coats, or lies on top of another surface, often spreading across it.

When to use it: Use "over" when describing a layer of something that is being placed to cover an area (e.g., blanket over the bed, gravel over the dirt).

4. "under" (There are ants under the front yard.)

Why it is used: "Under" is a preposition of place used to show that something is directly beneath or below a surface.

When to use it: Use "under" when an object or subject is physically lower than the top layer of something else (e.g., under the table, under the soil).

5. "behind" (Behind the front yard is a garden.)

Why it is used: "Behind" specifies a spatial relationship where one object is at the rear or back of another object.

When to use it: Use "behind" when using a primary object (the yard) as a reference point to show that something else is located further back (e.g., behind the house, behind the fence).

6. "in front of" (The front yard is in front of the house.)

Why it is used: "In front of" is a compound preposition used to establish a position directly ahead of or facing another object.

When to use it: Use "in front of" when orienting objects relative to the front face of another structure (e.g., in front of the building, in front of the car).

7. "through" (The path cuts through the front yard.)

Why it is used: "Through" shows movement entering one side of a 3D space or area, passing within it, and exiting another side.

When to use it: Use "through" when describing traffic, paths, or objects that bisect or cross inside a boundary from one end to the other (e.g., walk through the forest, drive through the tunnel).

8. "between" (The front yard is between the sidewalk and the garden.)

Why it is used: "Between" is used to position an object in the middle space that separates two other distinct objects or landmarks.

When to use it: Use "between" when you have exactly two reference points and want to show that your subject occupies the space separating them (e.g., between two trees, between Monday and Wednesday).

9. "after" (The grass is planted after the front yard is level.)

Why it is used: "After" is a preposition of time used to indicate chronological order.

When to use it: Use "after" when one event must be fully completed before the next event can begin (e.g., after lunch, after class).

10. "before" (The fence posts should be set before the front yard is leveled.)

Why it is used: "Before" is a preposition of time indicating that an action must occur prior to another action.

When to use it: Use "before" to establish prerequisites or order of operations in a timeline (e.g., before breakfast, before sunset).

11. "around" (The fence will go around the front yard.)

Why it is used: "Around" is used to describe a circular path or a boundary that encircles/surrounds an area.

When to use it: Use "around" when describing something that forms a perimeter or passes along the outer edge of a specific zone (e.g., around the track, around the block).
