Level Ordering Hypothesis

MORPHOLOGY: a hypothesis proposed in Siegel (1974) which takes the form in (i):

(i) Class I affixation
	   \/
    Word Stress Rules
	   \/
    Class II affixation
This hypothesis embodies the claim that affixation takes place in two linearly ordered blocks, which are separated by the word stress rules. EXAMPLE: the derivation of the English words productÝvity and prod˙ctiveness runs as follows. In the case of productivity, we first put together pro-, duct, -ive, and -ity (all Class I), and then we apply the stress rules (productÝvity). The derivation of productiveness is crucially different. First we put together pro-, duct, and -ive, then we apply the stress rules (prod˙ctive), and only then do we have the chance to add the Class II affix -ness, giving prod˙ctiveness. Since the affixation of -ness takes place after the stress rules have applied, it is correctly predicted that -ness cannot affect the stress already assigned to productive. Allen (1978) has replaced Siegel's Level Ordering Hypothesis by the more detailed Extended Level ordering Hypothesis.
