As nouns the difference between taxonomy and ylem
is that taxonomy is the science or the technique used to make a classification while ylem is in the big bang theory, the hot and dense plasma of which the cosmos consisted at the time of recombination in an early stage of its expansion and cooling, when the first atoms formed and photons decoupled, the source of the cosmic background radiation.

Usage notes
* The word ylem reappeared in popular books on science, following the discovery (in 1964-5) of the predicted (in 1948) cosmic background radiation and publication of its images composed from measurements by satellites (COBE in 1992 and WMAP in 2003).
