Italian words are divided into syllables as follows:
A single consonant goes with the following vowel.
Double consonants are divided.
Two consonants, the first of which is l, m, n, or r, are divided.
Otherwise, a combination of two consonants belongs to the following syllable.
The first of three consonants, except s, goes with the preceding syllable.
Diphthongs and triphthongs are never divided.

Diphthongs may occur in stressed or unstressed syllables. However, when a diphthong is broken by stress (the vowel i or u directly bears the stress), then the two vowels break into separate syllables.
