Correlative degree (chenân ... ke)

To express that a situation is "so [adjective/adverb]" that it causes a specific outcome, use the correlative structure چنان ... که (so ... that).

Place چنان directly before the adjective or adverb, and use که to introduce the resulting action or state. The result clause usually takes the indicative mood because it describes a factual consequence.

If the result clause requires a modal verb (like "couldn't"), the modal verb is indicative, followed by the usual subjunctive verb.
