Expert writing Tips
Best practice
Use "the fundamental cause" when you want to emphasize the deepest, most foundational reason behind a phenomenon. This implies a more thorough analysis than simply stating "the cause".
Common error
Avoid mistaking an immediate trigger for "the fundamental cause". The fundamental cause is the deep-rooted factor, while immediate triggers are merely the final events in a chain of causation. For example, a stock market crash might be the immediate trigger for an economic downturn, but excessive risk-taking could be the fundamental cause.
