The two simple rules for mastering that versus which
In short: Many people struggle with the nuances of relative pronouns, but the distinction often boils down to two specific grammatical constraints. This video from Khan Academy clarifies how to use these words correctly in Standard American English.
Grammarian David explains that the choice between "that" and "which" depends on punctuation and the subject of the sentence. Specifically, "that" is generally incompatible with commas, while "which" is typically avoided when referring to people.
Understanding these conventions helps maintain clarity in writing. While the lesson focuses on Standard American English, these rules serve as a foundational guide for general grammar and clear communication.
