'digitally-illiterate' originates from the combination of 'digital' and 'illiterate', where 'digital' refers to technology and 'illiterate' means lacking knowledge or education.

'digitally-illiterate' evolved from the increasing importance of digital skills in modern society, combining 'digital' with 'illiterate' to describe a lack of digital proficiency.

Initially, 'illiterate' meant unable to read or write, but in this context, it evolved to mean lacking digital skills.
