Etymology
The word 'carotene' is a direct scientific borrowing from German 'Carotin', which was coined in the 19th century. Its formation is transparently literal: the first element, 'carot-', is derived from the Latin word for carrot, 'carota', identifying the source from which the compound was first isolated. The second element, '-ene', is a standard chemical suffix denoting a hydrocarbon. Thus, the term's logic is straightforwardly descriptive, naming the "hydrocarbon from carrots." Its modern abstract meaning as a provitamin retains this direct link to its original, pigmentary source in plants like carrots, pumpkins, and sweet potatoes.
