If you're trying to describe something related to syllables, here are some possibilities:
* Syllabification: The process of dividing a word into syllables.
* Syllable: A unit of pronunciation consisting of a single vowel sound, with or without surrounding consonants.
* Syllabic: Relating to or consisting of syllables.
If you can provide more context or the source of the word "syllabant," I might be able to give you a more specific answer.
