'topic-focused' originates from the combination of 'topic' and 'focused', where 'topic' comes from Latin 'topica', meaning 'a place', and 'focused' from Latin 'focus', meaning 'hearth' or 'center'.

'topic' evolved from the Latin 'topica' through Old French 'topique', and 'focused' from Latin 'focus' through Middle English 'focussed'.

Initially, 'topic' meant 'a place' and 'focused' meant 'centered', but together they evolved to mean 'concentrated on a specific subject'.
