'historically-applied' originates from the combination of 'historically' and 'applied'. 'Historically' comes from 'history', which originates from Greek 'historia', meaning 'inquiry' or 'knowledge acquired by investigation'. 'Applied' comes from Latin 'applicare', meaning 'to attach' or 'to join'.

'Historically' evolved from the Old French 'historie', and 'applied' evolved from the Latin 'applicare'. The combination of these words into 'historically-applied' is a modern English construct.

Initially, 'historically' meant 'pertaining to history', and 'applied' meant 'put to practical use'. Together, they evolved to mean 'used in the past'.
