To "throw a monkey wrench into" something is slang for sabotaging or frustrating a project, plan, or situation. This idiomatic expression signifies the act of introducing a significant obstacle or problem that disrupts the smooth progress or execution of an endeavor.

Understanding the Slang Phrase

The phrase "to throw a monkey wrench into" vividly illustrates the act of causing disruption. It implies that an external, often unforeseen, element has been introduced, intentionally or unintentionally, which impedes the natural flow or anticipated outcome of events.

  • Core Meaning: It means to hinder, disrupt, or cause a setback for plans or processes.
  • Impact: The result is typically frustration, delay, or the complete derailment of an activity.

Origin of the Idiom

The origin of "throwing a monkey wrench into" something dates back to the early 1900s. This idiom stems from the concept of industrial sabotage, where a physical tool, such as a monkey wrench, would literally be thrown into machinery to disable or damage it, thereby halting production or causing significant disruption. The phrase then evolved to metaphorically describe any action that similarly disrupts plans or operations in a non-industrial context.

Practical Usage and Examples

The phrase is commonly used in various contexts, from business and politics to personal plans, whenever an unexpected hindrance arises.

Examples of Use:

  • Business Context: "The new regulation really threw a monkey wrench into our product launch schedule, forcing us to re-evaluate our timeline."

  • General Disruption: "The sudden change in policy threw a monkey wrench into the team's carefully laid out strategy for the quarter."

A classic example illustrating its meaning is: "The boss threw a monkey wrench into our plans when he said we'd have to work Saturday." In this scenario, the boss's decision directly sabotaged the employees' personal weekend plans.
