'function-focused' originates from the combination of 'function,' derived from Latin 'functio,' meaning 'performance or execution,' and 'focused,' from Latin 'focus,' meaning 'hearth or fireplace,' which evolved to mean 'center of activity or interest.'

The term 'function-focused' combines the words 'function' and 'focused,' which have been used in English since the 16th and 17th centuries, respectively.

Initially, 'function' referred to a specific task or role, while 'focused' meant concentrated. Together, they evolved to describe a concentrated emphasis on a specific role or purpose.
