Syllabication rules provide guidance on dividing words into their constituent syllables. Some key points: 1) Each syllable contains one vowel sound, with or without surrounding consonants. When reading a word, the mouth opens and closes once per syllable. 2) A single consonant between vowels typically goes with the second vowel, while two or more consonants may be split between the vowels. 3) Vowel sounds and letter combinations involving consonant blends are considered in dividing words into syllables according to standardized rules.
