Duhkha (n.) might ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠be translated "sour": life soured by our grasping at it, as milk turns sour when kept too long.

Duhkha (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠not "life is suffering" but the frustration of life as we usually live it — the special misery of attempting the impossible.
