• Corrected sentence: I feel so much better after I’ve been for a run in the park.

Explanation:

• মূল বাক্যটি I feel so better… বলা হয়েছে, যা ভুল।

• Reason: "so" cannot be used directly with the comparative adjective "better." We must use so much better.

• Rule: Before comparatives, use so much, not just "so."

Additional notes on “so”:

1. Comparison substitute:

   • When comparing: more so / less so can be used.

   • Example: The kitchen is very old-fashioned, the living room more so.

2. Degree adverb (to such a great extent):

   • Example: Using that camera is easy. Why is she making it so difficult?

3. Intensifier (very, very):

   • Example: That’s kind of you. Thanks so much for thinking of us.
