The term 'plant-sourced' combines 'plant,' from Old English 'plante,' meaning 'young tree or shrub,' and 'sourced,' from the verb 'source,' meaning 'to obtain from a particular source.'

'Plant' evolved from the Old English 'plante,' while 'sourced' comes from the Middle English 'soursen,' derived from Old French 'sourcer.'

Initially, 'plant' referred to any young tree or shrub, while 'sourced' meant 'to obtain.' Together, they now refer to materials derived from plants.
