Kean2 argues that deglottalization in Klamath is handled by two rules, sonorant deglottalization and obstruent deglottalization (applied in that order), and that the argument in Kisseberth3 against the simultaneous application principle of The Sound Pattern of English4 (henceforth SPE) is therefore invalid. Since there seems to be no disagreement about the data and the underlying representations, I assume here that the facts Kean reports are correct. In particular: (1) obstruents deglottalize before voiceless sonorants, before glottalized sonorants, and word-finally (but not before voiced nonglottalized sonorants). And (2) sonorants deglottalize before any consonant except strident obstruents (mol's pus); they do not deglottalize word-finally (sway' red deer). I agree with the spirit of Kean's idea of requiring more than one rule to handle these deglottalizations and also with her comment that Klamath deglottalization provides no crucial evidence against the SPE proposal of simultaneous application of phonological rules.
