Definition of the word instrumental

The word "instrumental" originates from the Latin word "instrumentum," meaning "means" or "tool." In the 14th century, the term referred to the instrument or means by which something was done or achieved. Over time, the meaning of the word shifted to emphasize the role of an instrument or tool in completing a task. In music, an instrumental piece is one that is performed solely by instruments, without vocals. In this context, the word "instrumental" highlights the primary role of the instruments in creating the music, rather than the use of human voice. In recent years, the term has also been used in a figurative sense to describe something that has a significant impact or influence on a particular outcome, such as an "instrumental" factor in a business decision.
