Grief is deep sorrow specifically caused by loss or bereavement, while sorrow is the broader feeling of deep sadness that can come from any cause. Think of grief as sorrow with a specific cause behind it: you grieve a death, but you can sorrow over almost anything that saddens you.
The core difference
Grief is sorrow tied to a loss; sorrow is the general feeling of deep sadness, whatever its cause.
- grief — deep sorrow, especially over a loss or bereavement: He never fully worked through his grief over his father's death.
- sorrow — deep sadness, especially over a loss, and also a verb meaning to feel or express that sadness: Her sorrow was clear on her face at the funeral.
How to tell them apart
Both words centre on loss, which is why they overlap so often, but grief leans specifically on bereavement, while sorrow works as a plainer, more general word for sadness. Sorrow can also be used as a verb, as in villagers who "sorrowed" over a loss, which grief cannot do.
Grief traces back to a Latin root meaning "heavy," the same root behind "grave" and "gravity" — a useful image for the weight grief carries. Sorrow comes from Old English and, despite how it looks, is not historically related to "sorry" or "sore."
