The Language of Sorrow

I wish we had a word in the English language that went hand in hand with the Latin word Doleo (also seen as: Dolere, Dolui, Dolitus)

1st Person Conjugation:

Doleo

Doles

Dolet

Dolemus

Doletis

Dolent

Doleo can be translated many ways. Simply, it means "I am sorry." It does not mean  I Apologize, however. Instead it is the I am sorry that we tend to say when we feel bad or grieve for another person's misery. It is a term of deep sympathy.
Doleo can also mean I grieve, I sorrow, I suffer, I feel pain.

Today I learned that a man I knew and that was friends with many friends of my own, died after battling with a serious health issue. I did not know this man. I met him once but I cannot say that I knew him because I feel it would not be considerate to those who truly knew this man as he was in this life. He was a teacher and a brother to many in this community in Alaska as well as in Canada and elsewhere.
I wanted to find the words to say to my friends who are grieving the loss of this man and found myself saying Doleo.
I am sorry. I grieve for you. I sympathize.
To my friends who did not spend 4 years studying a dead language, I am sorry might sound strange. It is, of course, not my fault that Big Bad Jim died. I do not have the power to cause such illness in others. So why would I be sorry? Our language is so limiting in this aspect.
Doleo.
I am so very sorry.
