Definition of fuse

The word "fuse" has multiple origins, but the most common sense of the word originated in the late 16th century from the Latin word "fusus," meaning "melting." This refers to the process of melting or burning out, as in a fuse blowing due to excessive electrical current. In the early 17th century, the word "fuse" began to be used to describe a device that melts or burns out when a specific condition is met, such as the breaking of a glass vial or the burning of a strip of fuse material. Today, the word "fuse" has expanded to include other meanings, such as a condition of being overcome with excitement or passion. However, its primary meaning remains related to the original concept of melting or burning out, often used in the context of electrical or mechanical devices.
