Overview
The expression -다고/라고 치다 is used to introduce a hypothetical situation or an assumption. It functions as a way to set up a premise for discussion, calculation, or argument, even if the premise itself might not be entirely true or certain. The verb 치다 in this context means "to consider," "to regard," or "to count as."
Usage
This grammatical pattern is employed when the speaker wants to temporarily accept a condition or statement as true for the purpose of exploring its implications. It's often used when you want to say, "Let's just assume X is true, and then what?" or "Even if we grant that X is the case, what follows?" It allows for a thought experiment or a conditional argument without necessarily confirming the truth of the initial statement. It's commonly followed by a question, a consequence, or a statement that evaluates the assumed situation.
