Definition

Adverb - Through repeated experimentation and learning from mistakes: This phrase describes a method of solving a problem, learning a skill, or discovering how something works by trying different approaches, observing the results, and adjusting based on what succeeds or fails, without necessarily having a complete theoretical plan to start.

Usage

This adverb phrase modifies a verb to describe how an action is performed. It is typically placed after the verb or at the end of a clause. - It describes a practical, hands-on, and often lengthy process of discovery. - It implies a lack of initial certainty or a formal guide.
