Prepositions and Their Relationships in English Grammar

Prepositions and the Relationships They Express

Prepositions are words that connect a noun, pronoun, or verb to another word in a sentence, showing the relationship between elements. They express various relationships, such as place, time, direction, or other abstract or logical connections. Common prepositions include "in," "on," "at," "under," "over," and "by."

Relationships Expressed by Prepositions

Prepositions can express relationships in several ways:

• How: Accuracy was increased by repeating the test. I fixed the light with a screwdriver.
• When: Jeremy has wanted to be a musician since childhood. The meeting resumes at 10:30 a.m.
• Where: The conference room is through that door. The crushing machine is located in the mechanics lab.

Common Prepositions

There are over 100 single-word prepositions in the English language, and many of these prepositions can be used to express more than one type of relationship. Some common prepositions you might encounter include:

Time Prepositions

• in (month/year), on (day), at (time), before, during, after, since, until

Location Prepositions

• under, over, above, below, between, in, out, on, at, by

Movement Prepositions

• to, into, towards, through, across, up, down, around, past

Other Relationship Prepositions

• for, by, from, of, as, with, about

Multi-word Prepositions

Sometimes, prepositions take the form of multi-word phrases. These combinations can also be combined with verbs to express physical or abstract relationships. For example, "in front of" can be used to describe a physical relationship, while "in favor of" can be used to express support for an idea.

Choosing the Right Preposition

The choice of preposition can change the meaning of a sentence, so it's important to use the right one. For example, "Of/for" can be used in different ways:

• The aim is to replicate the results of the engineering team.
• The engineering team produced the results.

Using Prepositions Correctly

Using prepositions correctly requires practice and careful attention. It's essential to consider the relationship you are trying to explain and consult a dictionary or use a proofreading service if needed.
