'vegetable-derived' originates from the combination of 'vegetable' and the suffix '-derived', where 'vegetable' refers to edible plants and '-derived' indicates origin or source.

'vegetable' comes from the Latin word 'vegetabilis', meaning 'growing, flourishing', and '-derived' is from the Latin 'derivare', meaning 'to draw off'.

Initially, 'vegetable' referred to any plant, but now it commonly refers to edible plants. 'Derived' has maintained its meaning of 'originating from'.
