Synonym discussion
Sense: verb/1
All four words describe experiencing sadness over a loss. 'Grieve' is the most common and natural choice for personal, private sadness that lasts over time — you can grieve alone in your room or with family at a funeral. 'Mourn' adds a social or ritual dimension: people mourn at funerals, wear black clothing, or observe a mourning period. 'Lament' is more literary and formal, often implying loud crying or poetic expression of regret ('the poem laments the loss of youth'). 'Sorrow' as a verb is rare in modern English and sounds very old-fashioned; it is far more common as a noun. For everyday use, choose 'grieve' for internal feeling and 'mourn' for public expression: 'She grieved for years after her son died' focuses on her ongoing sadness, while 'The nation mourned the president's death' describes a collective act.

Etymology
From Old French 'grever' meaning 'to burden, oppress, afflict', which came from Latin 'gravāre' meaning 'to make heavy' (from 'gravis' = heavy). The emotional sense of carrying a heavy weight of sadness developed in Middle English and gradually replaced the older physical meaning of 'burden'.
