The word "widely" means in a broad or extensive manner, covering a large area or having a wide range.
An antonym for "widely" could be "narrowly". When something is done narrowly, it is limited in scope or extent. For example, "The research was narrowly focused on a specific group of people, whereas the previous study had been conducted widely across different populations." Here, "widely" implies a broad reach and inclusiveness, while "narrowly" indicates a more restricted and specific approach.
Another antonym could be "sparingly". If something is done sparingly, it is done in a limited or frugal way. For instance, "The resources were used sparingly, in contrast to the previous project where they were distributed widely." In this case, "widely" suggests a generous and abundant distribution, while "sparingly" indicates a more conservative and limited use.
In conclusion, while "widely" conveys a sense of breadth and extensiveness, its antonyms like "narrowly" and "sparingly" express concepts of limitation and restriction. These words can be used to create contrast and add nuance to descriptions and discussions.
