'intellectually-focused' originates from the combination of 'intellectual' and 'focus', where 'intellectual' comes from Latin 'intellectus' meaning 'understanding' and 'focus' from Latin 'focus' meaning 'hearth' or 'center'.

'intellectually-focused' evolved from the combination of 'intellectual' and 'focus', which were used separately in Middle English and later combined in modern English.

Initially, 'intellectual' meant 'pertaining to the intellect', and 'focus' meant 'center of activity'. Together, they evolved to mean 'concentrated on intellectual pursuits'.
