'digital-friendly' originates from the combination of 'digital,' which comes from Latin 'digitalis,' meaning 'pertaining to fingers' (as digits), and 'friendly,' from Old English 'freondlic,' meaning 'kind or helpful.'

'digital' evolved from the Latin 'digitalis' through Middle English, while 'friendly' transformed from Old English 'freondlic' to its modern form.

Initially, 'digital' referred to numerical representation, but it evolved to mean anything related to technology. 'Friendly' maintained its meaning of being approachable or easy to use.
