'orderly-minded' originates from English, specifically the words 'orderly' and 'minded', where 'order' ultimately comes from Latin 'ordo' meaning 'row/arrangement' and 'mind' comes from Old English 'gemynd' meaning 'memory/attention'.

'orderly' developed from Middle English forms influenced by Old French 'ordre' (from Latin 'ordo'), producing 'order' and the adjectival suffix '-ly'; 'minded' is formed from 'mind' (Old English 'gemynd' → Middle English 'minde'/'mind') with the participial/adjectival '-ed' (hence 'minded'). These parts combined in Modern English to form the compound adjective 'orderly-minded'.

Initially the component words focused on 'arrangement' (order) and 'mental attention' (mind); over time the compound came to mean 'having a disposition toward being organized or methodical.'
