既然...就(jìrán...jiù)
Since... Then (Logical Deduction)
Structure Pattern
Explanation
既然 (jìrán) means "since" or "now that." It states a known fact or a premise that cannot be changed. It is usually paired with 就 (jiù), 也 (yě), or 还 (hái) in the second clause to draw a logical conclusion or make a suggestion based on that fact.
Key Difference from 因为 (Because):
- 因为 (yīnwèi) is for explaining the cause of a result (objective cause and effect).
- 既然 (jìrán) is for stating a premise to make a subjective suggestion or deduction (Since A is a fact, we should do B).
