'trait-focused' originates from the English word 'trait,' which comes from the Latin word 'tractus,' meaning 'drawn' or 'pulled,' and 'focused,' from the Latin 'focus,' meaning 'hearth' or 'center.'

'Trait' evolved from the Old French word 'trait,' meaning 'line' or 'feature,' and 'focused' from the Latin 'focus,' which was adopted into English in the 17th century.

Initially, 'trait' referred to a line or feature, but over time it evolved to mean a distinguishing quality or characteristic, while 'focused' retained its meaning of concentration or emphasis.
