چونکہ ... اس لیے
Presenting the Cause Before the Result
Since this is true → this follows.
How It Works
The چونکہ clause presents a reason the speaker is using. اس لیے then introduces the action, result or conclusion based on it.
The tenses depend on the situation. A past reason can explain a past decision; a present situation can support a future plan. The connector itself does not require one tense.
اس لیے makes the relationship easy to follow but need not appear in every چونکہ sentence. Contrast اگر, which sets a condition without itself asserting that the condition holds.
