8.6.1 Deaspiration
Dealing with the case of deaspiration first, this analysis assumes that this is yet another effect of the constraint OCPLar: Northern Pame disallows two aspirated consonants to be contiguous and therefore,
prefers an output in which it appears that some change has occurred. Basically, the OCPLar is similar to that regarding lateralization of [sg]. Recall in that analysis that
the optimal candidate did not contain a deletion of the grammatical morpheme, a violation of MAX-IO. The faithfulness of non-lexical affixes is a common theme in Northern Pame and is applicable here as
well. Thus, we can make a distinction of the laryngeal node on a lexical consonant versus a non-lexical
one. These are defined in 44 and 45. 44

‘Non-lexical output segments have input correspondents for Lar’ These faithfulness constraints are ranked so that the laryngeal node for lexical consonants will be
phonologically altered before non-lexical ones. 46

In 46, the input has two adjacent aspirated consonants. Candidate a fails due to a violation of OCPLar, and candidate b likewise fails because the surface form deletes aspiration from the non-
lexical consonant. Candidate c, therefore, wins by deaspirating the lexical consonant according to the minimal violation of IDENT:CLar

.
8.6.2 Deglottalization
The deletion of the laryngeal node is applicable in exactly the same way where an aspirated consonant prefixes to a glottalized consonant. Again, the surface form has a preserved non-lexical laryngeally
complex segment, but a delaryngealized i.e. deglottalized lexical consonant.
55
This is accomplished by delinking the lexical consonant from the laryngeal node.
