Morphology
polychotomous = dichotomous (semi-transparent) = poly + dichotomous
The meaning is clear once dichotomous is known, but the term is a technical learned formation and not fully obvious to an average learner.
Etymology
The word polychotomous comes from Greek parts: poly- meaning 'many' and -chotomy, the 'cutting into parts' idea you also see in dichotomy, where di- means 'two'. So polychotomous means 'divided into many parts', which is why it describes something with more than two categories.
