'theme-centric' originates from the combination of 'theme' and the suffix '-centric', where 'theme' refers to a subject or topic, and '-centric' means centered around or focused on.

'Theme' comes from the Latin word 'thema', which was derived from the Greek word 'thema', meaning 'a proposition or subject'. The suffix '-centric' is derived from the Greek word 'kentrikos', meaning 'pertaining to a center'.

Initially, 'theme' referred to a subject or topic, and '-centric' meant centered around. The combination has maintained its meaning of being focused on a particular theme.
