Expert writing Tips
Best practice
When using "necessitated by", ensure that the cause-and-effect relationship is clear to enhance the clarity of your writing. For example, instead of saying "Changes were made necessitated by circumstances", be more specific: "The budget cuts were necessitated by a decrease in revenue".
Common error
Avoid using "necessitated by" when the relationship isn't a direct cause and effect. For instance, don't say "The project was necessitated by interest" if the project was simply inspired, not strictly required. Use words like 'inspired' or 'influenced' instead.
