2.) Occasioning pain or grief; painful (Webster's Revised Unabridged Dictionary).
Etymology: Middle English, from Old French doloros, from Late Latin dolorosus, from dolor, pain, from dolare, to suffer, feel pain.
"As soon as I had heard those souls tormented,
I bowed my face, and so long held it down
Until the Poet said to me: 'What thinkest?'
When I made answer, I began: 'Alas!
How many pleasant thoughts, how much desire,
Conducted these unto the dolorous pass!'"
(Divine Comedy by Dante Alighieri, Henry Wadsworth Longfellow (trans.), 1867)
