Through vs. Over: What's the Difference?

Edited by Harlon Moss || By Janet White || Updated on November 22, 2023
Through implies movement from one side to another within something or completion of a process, while over indicates movement above something or a position higher than something else.

Key Differences

Through typically suggests a motion entering and then exiting something, indicating a passage within or among. It often conveys a sense of permeation or traversal inside a boundary or medium. Over, in contrast, implies a movement above the surface of something, suggesting elevation and a position on top or covering something.
When used temporally, through indicates duration within a period, from start to finish. It conveys a sense of continuity over time until completion. Over, used temporally, often suggests a period throughout which something occurs or is valid, but can also imply conclusion or termination.
In communication contexts, through is used to describe a medium or channel by which information is conveyed. It implies directness and a connection between points. Over, on the other hand, can be used to indicate transmission above a medium, like a signal over the airwaves, but also conveys a sense of authority or supervision in certain contexts.
Through can also express the cause or means by which something happens, indicating a process or sequence. Over, alternatively, can denote control, superiority, or an excess amount, often used in contexts of hierarchy, dominance, or completion.
Through conveys a sense of movement amidst or within boundaries, like moving through a tunnel. Over, while describes a position or movement that is higher than something else, as in flying over a mountain.
