How would I go about saying: "I am not at liberty to say" or "I am not at liberty to discuss" It occurs to me that this would be an useful phrase to politely decline someone who is trying to pry.  I'm l a beginner, so it's hard for me know how to translate this.
“I am not at liberty to say” or “I am not at liberty to discuss”


(這個/ 這件事) 我不方便說 = (This/ on this topic,) I am not at liberty to talk

(這個/ 這件事) 我不方便討論 = (This/ on this topic,) I am not at liberty to discuss

'不方便' literally means 'not convenient'  (as an adverb, it means ‘cannot conveniently) - it implies 'cannot freely'. It is a polite way to refuse to make any comment
