Unravel

Return to > Dictionary

1. Definition + Rich Everyday Explanation

Unravel (verb) = to undo twisted or tangled threads; or more commonly, to solve a mystery, explain something complicated, or cause something to fall apart and fail.

This word starts with the literal picture of pulling apart a knotted ball of yarn — threads coming undone strand by strand. That’s the original meaning: separating what’s tangled.

But the metaphorical meanings are far more common today. One is positive: solving or clarifying something complex, like detectives unraveling a case or scientists unraveling DNA secrets. The other is negative: something falling apart gradually, like plans unraveling under pressure or a relationship unraveling over lies.

In real life, “unravel” often describes processes — mysteries getting solved step by step, or situations deteriorating bit by bit. It signals gradual change, either toward understanding or toward chaos. People use it when things feel intricate and the outcome hangs on small details coming loose.

Examples from the street:

• “The detective finally unraveled the alibi” → pieced together clues to expose the lie
• “Their marriage began to unravel after the move” → slowly fell apart with growing distance
• “She sat quietly unraveling the old sweater” → literally pulling yarn apart to reuse it

2. Most Common Patterns

• unravel + noun (mystery/secret/plot) → solve or figure out something complicated
• begin/start to unravel → the process of falling apart or solving starts
• something unravels → a situation or plan deteriorates gradually
• unravel under + noun (pressure/stress) → fall apart because of a force
• quickly/slowly unravel → describe the speed of the change
