Why "broaden" doesn't have a direct adjective counterpart:
* "Broaden" implies a process: It describes the action of making something wider or more comprehensive.
* Adjectives describe qualities: They describe a noun's attributes, not a dynamic change.
Alternatives depending on the context:
* Broad: This is the most common and straightforward option if you want to describe something that is wide, expansive, or comprehensive.
* "The course offered a broad range of topics."
* Wider: Emphasizes the expansion of something.
* "The new policy has a wider scope than the previous one."
* Comprehensive: Indicates inclusiveness and thoroughness.
* "The research presented a comprehensive analysis of the issue."
* Expansive: Describes something that is large, wide-ranging, and open.
* "The writer's imagination is expansive."
* Extensive: Indicates a large scale or scope.
* "The company has extensive operations across the globe."
Examples:
* Instead of "broadening the scope of the project," you could say:
* "The project's scope is now wider."
* "The project now has a more comprehensive scope."
The best choice depends on the specific meaning you want to convey.
