'field-oriented' originates from the combination of 'field,' meaning 'an area of activity or interest,' and 'oriented,' meaning 'directed towards or focused on.'

'Field' and 'oriented' have been used in English since the Middle Ages, with 'field' referring to an open land area and 'oriented' deriving from the Latin 'orientare,' meaning 'to arrange or direct.'

Initially, 'field' referred to open land, but in modern usage, it often refers to a specific area of study or work. 'Oriented' has maintained its meaning of direction or focus.
