The word "induction" originates from Latin inductio (a leading in), derived from inducere (to lead in). The morpheme in- means "into," and ducere means "to lead," reflecting the idea of guiding or introducing something. Over time, it expanded to include logical reasoning (leading to conclusions) and electromagnetic phenomena (leading to a state). The suffix -ion nominalizes the action.
