IPA: /dɪˈsɪl.ə.bəl/
KK: /dɪˈsaɪləbəl/
A word that has two separate sounds or beats, known as syllables.
The word 'happy' is a disyllable because it has two syllables: 'hap' and 'py'.
Disyllable → It is formed from "di-" (from Greek "dis", meaning two) and "syllable" (from Greek "syllabē", meaning a unit of speech). The word "disyllable" refers to a word that consists of two syllables.
Think of 'di-' meaning 'two' and 'syllable' as a unit of speech — so a disyllable is a word made up of two speech units.
