Misused word

important

Alternatives
large, substantial, significant.

Explanation
“Important” is often wrongly used to mean “big” (“the most important power station in France”); it actually means: “strongly affecting the course of events or the nature of things” or “having or suggesting a consciousness of high position or authority.”

Example
Avoid “The annual accounts give detailed information on the financial corrections confirmed, implemented and to be implemented and explain the reasons for which an important amount is still to be implemented.”

Use “The annual accounts give detailed information on the financial corrections confirmed, implemented and to be implemented and explain the reasons for which a significant amount is still to be implemented.”
