'fundamental-focused' originates from the combination of 'fundamental' and 'focus', where 'fundamental' comes from Latin 'fundamentalis', meaning 'of the foundation', and 'focus' from Latin 'focus', meaning 'hearth' or 'fireplace'.

'fundamentalis' transformed into the Old French 'fondement', and eventually became the modern English word 'fundamental'. 'Focus' retained its form from Latin to English.

Initially, 'fundamental' meant 'of the foundation', and 'focus' meant 'hearth'. Over time, 'focus' evolved to mean 'center of activity or interest', and 'fundamental' retained its original meaning.
