 The analysis of synonymy, polysemy, hyponymy, and hypernymy is inherent to taxonomy and ontology in the information-science senses of those terms.It has applications in pedagogy and machine learning, because they rely on word-sense disambiguation.The word is borrowed from Latin "synōnymum", in turn borrowed from Ancient Greek "synōnymon" (), composed of "sýn" ( 'together, similar, alike') and "-ōnym-" (), a form of "onoma" ( 'name').
