Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 6, 2023
"By" often indicates the means or agent of an action, while "through" typically denotes movement within or completion of an action.
Key Differences
When used as a preposition, "by" can indicate the agent or means of an action. For instance, "The painting was done by an artist" shows who performed the action. On the other hand, "through" can signify movement from one end or side to another, like "He walked through the door."

Another distinction arises when "by" is used to highlight a method or means, for example, "She traveled by train." Conversely, "through" might highlight the idea of thoroughness or completion, showcased by "He went through all the documents."
