An interesting development in the phonology of Traditional New Mexico Spanish (TNMS) 1 is the formation of syllabic consonants through the absorption of an adjacent vowel). The effect of this process is that a syllable formerly headed by a vowel is now headed by a consonant. This sound change is quite unexpectedgiven that under any version of the sonority scale, consonants are less sonorous than vowels.Since the nucleus is the peak of sonority within the syllable, one would expect the segment of higher sonority to be preferred in the role of syllable head; yet it is exactly in the opposite direction that the formation of syllabic consonants advances. In TNMS, an additional property of this process is that the nuclear vowels that are replaced by consonants are high vowels bearing primary or secondary stress. Moreover, among stressed high vowels, the ones that yield their syllabicity to an adjacent consonant are those that belong to affixes or function words. following Coleman (2001) and Espinosa (1909Espinosa ( /1930Espinosa ( , 1925, that the vowel that disappears in
