The term 'practically-modified' is a compound word formed from 'practically' and 'modified'. 'Practically' originates from the Latin word 'practicus', meaning 'practical', and 'modified' comes from the Latin 'modificare', meaning 'to measure' or 'to limit'.

'Practically' evolved from the Old French 'practique', while 'modified' transitioned from the Old French 'modifier'. The combination of these words into 'practically-modified' is a modern English construct.

Initially, 'practically' meant 'in a practical manner', and 'modified' meant 'changed'. Together, they convey the idea of being almost completely changed.
