More accurately delinking does not necessarily entail immediate deletion although it is usually assumed that any melodic material not associated to a skeletal point at the end of a derivation is erased at that stage one aspect of an operation known as Stray Erasure .107 One type of evidence supporting this view has to do with the manner in which phonological processes interact with morpho-syntactic structure. Let us remind ourselves of the assumption outlined in that processes occur cyclically that is their conditions are repeatedly checked through a succession of morpho-syntactic domains which are visible to the phonology. A given process which results in the suppression of melodic material is going to have quite different cyclic effects according to whether it is cast in terms of deletion of delinking without deletion. Any material that is deleted on a particular cycle will not be recoverable on a later cycle one of the consequences of a principle known as the Strict Cycle Condition .108 On the other hand if melodic material is delinked but not deleted on a given cycle it is potentially recoverable should different licensing conditions become available on a subsequent cycle. That at least is the prediction which follows from the independence view of delinking and deletion and it appears to be by and large correct as we will now Let us now try to specify the precise conditions under which lenition occurs in each of our illustrative systems. As summarized in 64 the distributional difference between the two glottalling systems A and B resides in the fact that lenition in A only occurs domain-finally and then only if a consonant or pause follows. Under the ambisyllabicity approach the latter conditions are implicitly identified as the context in which t fails to undergo resyllabification into a following onset by rule 68 . Under the licensing account since t already occupies an onset the conditioning can only be expressed in
