- suffix used to form nouns meaning a study of the totality of something; e.g. genomics, proteomics
-oma + -ics, both ultimately from Ancient Greek (Wiktionary)
The -omics suffix is most comfortable following an n: you often heard Nixonomics, Reaganomics and Clintonomics but not Fordomics, Carteromics or Bushomics.
