It cannot be a root word cause a root word is a basic word with no prefix or suffix added to it. A consonant is a speech sound that is not a vowel, the word "incumbent" contains vowels like "i","u","e". A syllable contains one vowel sound, here we get to see three vowels., so its also not a syllable.
Prefix and suffix is the final answer.
