1. Definition + Rich Everyday Explanation
Transgression (noun) = an act that goes beyond accepted limits, rules, or moral boundaries.
Literally, the word comes from Latin meaning to step across or go beyond. A transgression is when someone crosses a line — whether that line is a law, a social norm, a moral code, or a personal boundary.
In everyday modern English, transgression carries a sense of violation and wrongdoing. It’s stronger than “mistake” because it implies the person knew the boundary existed and crossed it anyway. The word often appears in formal, religious, legal, or serious moral contexts, but people also use it more casually to describe moments when someone overstepped or did something they shouldn’t have.
When people talk about transgressions, there’s usually an underlying sense of guilt, accountability, or consequences. It’s not just about breaking a rule — it’s about the weight of having done so.
Examples from the street:
- “He apologised for his past transgressions” → he acknowledged serious mistakes he made before
- “That kind of transgression won’t be tolerated” → crossing that line will have consequences
- “She saw it as a minor transgression” → a small overstep, not a major violation
2. Most Common Patterns
- a transgression against + noun → a violation of something (rules, values, person)
- commit a transgression → do something that crosses a line
- forgive a transgression → let go of someone’s wrongdoing
- past transgressions → previous wrongdoings or mistakes
- minor/serious transgression → describes the severity of the violation
3. Idioms
- cross the line → go beyond what is acceptable, commit a transgression
Example: “He crossed the line when he insulted her family.”
- overstep the mark → go beyond acceptable limits or boundaries
Example: “She overstepped the mark by reading his private messages.”
