'marine-focused' originates from the Latin word 'marinus,' meaning 'of the sea,' combined with the English word 'focus,' meaning 'center of interest.'

'Marine' evolved from the Latin 'marinus' through Old French 'marin,' while 'focus' comes from Latin 'focus,' meaning 'hearth' or 'fireplace,' and later 'center of activity.'

Initially, 'marine' meant 'of the sea,' and 'focus' meant 'center of activity.' Together, they evolved to mean 'centered on the sea.'
