'problem-oriented' originates from the combination of 'problem' and 'oriented', where 'problem' refers to a matter or situation regarded as unwelcome or harmful and needing to be dealt with, and 'oriented' means directed towards a particular goal or focus.

'problem-oriented' evolved from the combination of the words 'problem' and 'oriented', which were used separately in English before being combined to describe a focus on solving issues.

Initially, it meant 'focused on problems', but over time it evolved into its current meaning of 'focused on solving problems'.
