'grateful-centered' originates from the English word 'grateful,' which comes from the Latin word 'gratus,' meaning 'pleasing' or 'thankful.'

'gratus' transformed into the Old French word 'grate,' and eventually became the modern English word 'grateful.' The suffix '-centered' is added to denote focus or emphasis.

Initially, 'gratus' meant 'pleasing,' but over time it evolved into 'grateful,' meaning 'thankful' or 'appreciative.'
