'quality-centered' originates from the English word 'quality' combined with 'centered,' where 'quality' refers to the standard of something as measured against other things of a similar kind, and 'centered' means focused or concentrated on a particular thing.

'quality' comes from the Latin word 'qualitas,' and 'centered' is derived from the Latin 'centrum,' meaning 'center.'

Initially, 'quality' referred to the nature or essence of something, but over time it evolved to mean the standard or grade of something.
