'oral-centric' originates from the combination of 'oral,' derived from Latin 'oralis,' meaning 'pertaining to the mouth,' and 'centric,' from Greek 'kentrikos,' meaning 'pertaining to a center.'

'oral' changed from the Latin word 'oralis' and 'centric' from the Greek word 'kentrikos,' eventually forming the modern English word 'oral-centric.'

Initially, 'oral' meant 'pertaining to the mouth,' and 'centric' meant 'centered.' Over time, 'oral-centric' evolved to mean 'focused on oral communication.'
