This document discusses syllabication, or the process of breaking words into syllables. It defines syllabication and notes that hyphens and periods are often used to separate syllables in writing. It then outlines six principles of syllabication: the obligatory onset principle, the stress principle, the legality principle, the irregular coda principle, the sonority cycle principle, and the resyllabification principle. The document also lists common syllable patterns and concludes that it is important to understand the various processes involved in syllabication to teach syllable division correctly.
