Moraic coda sonority in Chilean Spanish

Abstract

This paper discusses coda lenition phenomena in Chilean Spanish, seeking to create a unified analysis for coda obstruent gliding and /s/-reduction. The paper invokes Moraic Theory to motivate lenition of certain segments in coda position. Using Harmonic Serialism, a serial variant of Optimality Theory, Chilean Spanish is shown to have a minimum sonority requirement on coda segments, and lenites insufficiently sonorous segments. /s/ is shown to place-delete to [h] to avoid sonority restrictions. The lack of /ʔ/ causes obstruents to diverge their derivation from that of /s/. Lenition to glottal segments is preferred, but gliding occurs if this is impossible.
