This study investigates the dynamic aspects of laryngeal co-occurrence restrictions whose static aspects have been evaluated. By examining word-initial tensification and adverbializer allomorphy in Korean, we show that a laryngeally marked feature tends to co-occur with the same features in word formations. A tense consonant in the second syllable facilitates the tensification of the word-initial consonant, and an aspirated consonant in an adjectival stem requires ?hi as an adverbializer rather than ?i. The analysis of the entire lexicon shows that these patterns are correlated with those in the lexicon. Based on these results, we argue that Korean has an assimilation type restriction (Gallagher 2010), contrary to Ito (2014). This study provides insight about how the dynamic and static aspects of the restrictions interact to form specific patterns in the lexicon.
