Disaggregation
Disaggregation is an unlovely word. I suggest the more proper, elegant and beautiful “abgregation”. O (thou sayest) wherefore? Well “aggregation”, of course, is “ad” [into] + “greg” [herd]. We get egregious [apart from the common herd] from the same root, and gregarious [herdy]…
Anyways why pile on the prefixes? Just replace “ad” with “ab” and you get the notion of unbundling. This usage is smiled upon by no less an authority than Bailey, tho admittedly the OED rather superciliously claims that abgregation was “App. never used”.
