182 [S$] also results from reduction of sequences of /s/ and /j/ in Salinas. The neutralization of /ch/ and /sj/ is evidence of the instability of the three phonemes as indi- cated in Chapter 3.) In all roots and in the suffix -cha- /ch/ is preceded by a vowel. Reduction to [s] is obligatory in some morphemes, optional in others, and varies dialectally. Examples: Nouns: pachpa [paspa] ‘same’ (most dialects) pichg'a [picg'a] 'five' (Calacala) ichk'a [ick'a ~ iSk'a] ‘little’ (Sitajara) Verbs: jich'i- ‘carry grains in the hand' + zp tia- momentaneous > oe vw jich.t'a [jict'a] (Morocomarca) [jist'a] (Salinas) (In this example /ch'/ loses glottalization before the consonant-requiring suffix -t'a-, in rapid speech.)
