'historically-integrated' originates from the combination of 'historically' and 'integrated'. 'Historically' comes from 'history', which originates from the Greek word 'historia', meaning 'inquiry' or 'knowledge acquired by investigation'. 'Integrated' comes from the Latin word 'integrare', meaning 'to make whole'.

'Historically-integrated' evolved from the combination of 'historically' and 'integrated', which were used separately in Middle English and later combined in modern English.

Initially, 'integrated' meant 'to make whole', and 'historically' referred to 'pertaining to history'. Together, they evolved to mean 'combined over time with historical significance'.
