假如 + Condition, 就 + Result
假如 (jiǎrú) means "if" or "supposing that" and introduces a hypothetical condition. It is slightly more formal than 如果 (rúguǒ) and is commonly paired with 就 (jiù) in the result clause. This word is used in both spoken and written Chinese to discuss hypothetical or imagined situations.
