disaggregation
|dis-ag-gre-ga-tion|
/dɪsˌæɡrɪˈɡeɪʃən/
(disaggregate)
break into parts
Etymology
'disaggregation' originates from Latin elements, specifically the prefix 'dis-' and the verb 'aggregare', where 'dis-' meant 'apart, away' and 'aggregare' came from 'ad-' meaning 'to' plus 'gregare' (from 'grex') meaning 'flock' or 'group'.
'disaggregation' developed as a formation in English from the verb 'disaggregate' + the noun-forming suffix '-ion'. The verb traces to Late Latin 'disaggregare' (or related Medieval Latin forms) and through Middle English formations such as 'disagregacioun' evolved into modern English 'disaggregation'.
Initially it referred broadly to the action of separating what had been aggregated ('to separate from the group'), but over time it has been applied more specifically in technical contexts (e.g., data, economics) to mean breaking aggregate measures into detailed subcomponents.
