'ocean-centric' originates from the combination of 'ocean' and the suffix '-centric', where 'ocean' refers to the vast body of saltwater and '-centric' means 'centered around'.

'Ocean' comes from the Old French 'occean', from Latin 'oceanus', from Greek 'ōkeanos'. The suffix '-centric' is derived from the Greek 'kentrikos', meaning 'pertaining to a center'.

Initially, it meant 'centered around the ocean', and this meaning has remained consistent in modern usage.
