How it's used
This adverb describes an action done with great intensity, speed, or without any sign of stopping. It often implies a sense of recklessness or lack of restraint, as if the person has lost control or is obsessed with completing the task. It is frequently used to describe eating, talking, or working.
Examples
As soon as he saw me, he started talking non-stop.

Common mistake
Learners often confuse this with just working hard, but it carries a specific nuance of doing something in a frantic or repetitive manner. It is not used for positive, steady progress, but rather for actions that feel excessive or unbridled.
