'troglodyte' originates from Greek, specifically the word 'trōglodutēs,' where 'trōglē' meant 'hole' and 'dyein' meant 'to enter.'

'trōglodutēs' transformed into the Latin word 'troglodyta,' and eventually became the modern English word 'troglodyte' through Middle English.

Initially, it meant 'cave dweller,' but over time it evolved to also mean someone who is out of touch with modern society.
