Here are some examples:
* "The team won decisively, scoring three goals in the first half." This means they won with a clear margin and demonstrated dominance.
* "She answered the question decisively, leaving no room for interpretation." This means she provided a clear and confident response.
* "The judge ruled decisively in favor of the plaintiff." This means the judge made a clear decision without ambiguity.
In short, "decisively" suggests a strong and unwavering action or statement.
