'哭诉' is a compound verb meaning 'to cry while telling one's grievances' — it vividly captures the act of speaking about pain, injustice, or hardship amid tears. The first character 哭 (kū) means 'to cry', expressing intense sorrow or distress; the second 诉 (sù) means 'to tell', 'to complain', or 'to appeal', often with an emotional or pleading tone. Together, they emphasize not just crying or just speaking, but the inseparable fusion of weeping and verbalizing suffering — typically in moments of vulnerability, helplessness, or urgent need for empathy or redress.

This word appears frequently in literature, film, news reports, and everyday speech when describing someone recounting trauma, unfair treatment, or deep personal loss. It carries strong emotional weight and implies sincerity, urgency, and often a plea for understanding or assistance. Unlike neutral terms like 'complain' or 'explain', 哭诉 suggests raw, unfiltered emotion — the speaker is too overwhelmed to separate feeling from speech.
