'dialogue-centered' originates from the combination of 'dialogue' and 'centered', where 'dialogue' comes from the Greek word 'dialogos', meaning 'conversation', and 'centered' implies being focused or concentrated on a particular aspect.

The term 'dialogue' evolved from the Greek 'dialogos' to the Latin 'dialogus', and eventually became the modern English 'dialogue'. The word 'centered' has been used in English since the 16th century to denote focus or concentration.

Initially, 'dialogue' meant 'conversation between two or more people', and 'centered' meant 'focused'. The combined term 'dialogue-centered' retains this meaning, emphasizing a focus on conversation.
