The linguistic taxonomy (Greek taxis 'order', -nomia 'administration') is the teaching of the methods for the formation of classes under the aspect of the similarity relationships between the terms to be classified ( taxon , Pl. Taxa . Cf. also grammat. Taxem ) . The linguistic taxonomy developed from the numerical taxonomy in mathematics and is increasingly used in dialectology and language typology .
Some authors also speak of taxometry and mean the procedures of US structuralism in a derogatory way .
