View source for Class I/II affix

In phonology and morphology, '''class I/II affix''' is a classification of (English) affixes. 

===Example===
The English Class I affixes can cause [[stress]] shift (''párent-paréntal, prodúctive-productívity''), while their class II counterparts are stress neutral (''párent-párenthood, prodúctive-prodúctiveness''). Furthermore, class I affixes may appear inside class II affixes, but not vice versa (''*hopefulity''). This generalization is usually referred to as the [[Affix Ordering Generalization]].

===Comments===
Class I and Class II affixes can be distinguished in terms of their different phonological and morphological properties. 
The distinction between Class I and Class II affixes is equivalent to that between formative-boundary and word-boundary affixes (Chomsky & Halle, 1968), Level I and Level II affixes (Pesetsky 1979, Kiparsky 1982), and Stratum I and Stratum II affixes (Halle & Vergnaud 1987).
