phrase

to cause a small action or event that leads to much bigger and often unexpected results later.

  • One late email triggered the butterfly effect.
  • A small delay can trigger the butterfly effect.
  • That tiny mistake triggered the butterfly effect.

Adinary Nuance

This phrase is not the same as cause or lead to. Those are general and neutral. Trigger the butterfly effect adds the idea that the first event is small, but the later result becomes much bigger and harder to predict. Writers use it when they want to stress chain reactions, not just a simple result.
