Meanings

Adverb

  1. by experiment or trial, especially as part of research

Beyond the definition

Imagine a chef trying out a new recipe. They do not just assume it will taste good; they test different ingredients and methods until they find what works. That is the essence of "experimentally": doing something by using tests or trials to see how well it works. It often suggests a process of discovery, common in science but also possible in art, business, or everyday life. You might try a new route to work experimentally to see whether it saves time, or an artist might work experimentally with unusual materials.

The word hints at a deliberate attempt to learn through doing, not just blindly following instructions, but actively testing an idea and watching the results. Think of it as "trying something out" for a clear reason. A scientist might say they are "experimentally verifying" a theory, meaning they are running controlled tests to show whether it is true or false.
