overstep

Overstep is a verb that means to go beyond a boundary, limit, or accepted standard. It can also describe the physical act of stepping over something. In extended use, it conveys exceeding what is appropriate, proper, or authorized.

The word combines over- (beyond) with step, and has been used since earlier English to mean surpassing a limit. The phrase overstep the mark is an older idiom still in use.

Common usages include overstep the bounds or limits, overstep one's authority, and overstep the line. The phrase overstep the mark refers to going too far in behavior or speech. For example, The manager overstepped his authority by signing the contract; It would be overstepping the line to publish private data.

Legal and ethical contexts: When officials or organizations overstep statutory powers, actions may be challenged as ultra vires or unethical; courts may invalidate decisions or require remedies. In everyday life, overstepping boundaries can harm trust and relationships and may lead to consequences or sanctions.
