A word is the smallest linguistic unit capable of conveying meaning independently, yet its definition remains contested across linguistic theories. From phonological segments to orthographic markers, the concept spans multiple analytical levels. Authors like Bertrand Russell examined words as physical entities intertwined with meaning, while John Stuart Mill emphasized their limitations in capturing sensory experiences.
William James underscored how individual terms, when isolated, fail to evoke the full context of a sentence. These varied perspectives reveal the word’s dual role as both a structural element of language and a vessel for human thought, bridging the tangible and abstract in communication.
