'gratitude-centered' originates from the English word 'gratitude' combined with the suffix '-centered', where 'gratitude' means 'the quality of being thankful' and '-centered' implies 'focused on'.

'gratitude' comes from the Latin word 'gratitudo', and '-centered' is a modern English suffix used to denote focus or emphasis.

Initially, 'gratitude' meant 'thankfulness', and '-centered' meant 'focused on'. The combination has retained its meaning of being focused on thankfulness.
