Words are broken into syllables based on the vowel sounds there are in the word (not vowels, but vowel sounds).
1) Closed syllable: vc/cv
Makes the first vowel short.
2) Open syllable: v/cv
Makes the first vowel long.
3) Prefixes and Suffixes
Separate prefixes and suffixes from base words.
4) Compound words

5) Vowel blends stay together.
6) Silent e at the end of the word stays with the other letters.
7) Le at the end of a word is not separated.

Example: base/ball or sun/shine
Example: clean/er (ea stays together)
