'logical' originates from Greek, specifically the word 'logikos,' where 'logos' meant 'reason' or 'word.' 'Focused' comes from Latin 'focus,' meaning 'hearth' or 'fireplace,' which evolved to mean 'center of activity or interest.'

'Logikos' transformed into the Latin 'logicus,' and eventually became the modern English word 'logical.' 'Focus' was adopted into English from Latin, maintaining its meaning of 'center of activity.'

Initially, 'logical' meant 'pertaining to reason,' and 'focused' meant 'centered on a point.' Over time, 'logical-focused' evolved to mean 'having a rational and systematic approach.'
