electrode
UK: ɪˈlɛktrəʊd | US: ɪˈlɛktroʊd
n. a conductor through which electricity enters or leaves an object, substance, or region.
The word "electrode" combines "electro," derived from the Greek "ēlektron" (amber, associated with static electricity), and "de," a shortened form of "hodos" (Greek for "way" or "path"). Coined in the 19th century, it reflects the function of a conductor as a pathway for electric current. The term elegantly merges ancient Greek roots to describe a modern scientific concept.
