'tech-savvy' originates from the combination of 'tech,' a short form of 'technology,' and 'savvy,' which comes from the Latin word 'sapere,' meaning 'to be wise.'

'savvy' changed from the Spanish word 'sabe,' meaning 'he knows,' and eventually became the modern English word 'savvy.'

Initially, 'savvy' meant 'to know,' but over time it evolved into its current meaning of 'having practical knowledge or understanding.'
