The quality, state, or system of having or using two syllables; the practice of organizing words into two-syllable units.
From dissyllabic + -ism (suffix denoting a system, practice, or condition). Coined in linguistic terminology to describe a characteristic of language structure.
The -ism suffix turns qualities into systems or ideologies—you can have 'syllable' (the thing), 'syllabic' (the quality), 'syllabism' (the system or practice), showing how English endlessly creates new abstraction levels.
