The consonant /n/ can appear as a syllable and bear a high or low tone, but not a falling tone. High-toned /ń/ actually represents an underlying syllable, /nÍ/. There are four possible contours for Vowel-/n/ and /n/-/n/ combinations: Low-high, High-low, High-high, and Low-low. The contours are illustrated in the following table:
(Modified from Tuttle & Sandoval 2002, p. 109)
/n/ may occur between /t/, /ʔ/, or /n/ and any stem-initial consonant, but when /n/ occurs alone before a stem-initial consonant, it forms a syllable of its own. When preceded by another prefix consonant, /n/ may or may not be judged to form a syllable by native speakers of Jicarilla.
Jicarilla has 16 vowels:
All vowels may be
The long high front oral vowel is phonetically higher than its nasal and short counterparts ([iː] vs. [ɪ, ɪ̃, ɪ̃ː]). The short back vowel is higher than its long and nasal counterparts ([ʊ] vs. [oː, õ, õː]). The short low vowel is higher than its long and nasal counterparts ([ə] vs. [aː, ã, ãː]).
Nasal vowels are indicated by underlining in the Jicarilla orthography.
Jicarilla has three different tones: high, low, and falling.
High tone is indicated with an acute accent. Low tone is unmarked. Falling tone is indicated by a sequence of acute-accented vowel and an unmarked vowel.
Syllables may be constructed as CV, CVC, or CV:C (C – Consonant; V – Vowel) depending on the morphology of a sequence. Onset may be any consonant, but coda consonants are limited to /ʔ/, /l/, /ɬ/, /ʃ/, /h/, /s/and /n/.
A study of the durational effects of Jicarilla Apache show that morphology and prosody both affect and determine the durational realization of consonants and syllables. It was found that in a recording of a passage read by native speakers stem, suffix, and particle syllables were found to be longer than prefix syllables, but there is not enough a distinction to see difference in duration. Syllables at the end of phrases were lengthened differently from syllables lengthened because of stress; this is in regards to a ratio of onset lengthening to rhyme lengthening. This study was only a beginning to analysis of Apachean language prosody.
The Athabaskan morphophonological process known as the "d-effect" occurs when 1st pl/dual iid- is prefixed to a verb stem. The following examples are taken from Phone, Olson and Martinez 2007: 39:
-iid- + classifier [ƚ] → [ƚ] ex. ‘óoƚkai’ (< /’o-iid-ƚ-kai’/) ‘we two count it’ -iid- + stem initial [ʔ] → [t’] ex. hit’aaƚ (< /hi-iid-‘aaƚ/) 'we two chew it’ -iid- + stem initial [m] → [h] ex. hiihmas (< /hi-iid-mas/) ‘we two are rolling’ -iid- + stem initial [n] → [h] ex. goohndé (< /go-iid-ndé/) 'we two shout’ -iid- + stem initial [y] → [d], [dz] ex. hiidá (< /hi-iid-yá/) ‘we two eat it’ -iid- + stem initial gh [ɣ] → [g] ex. hiigá (< /hi-iid-ghá/) ‘we two kill them’ -iid- + stem initial [z] → [dz] ex. naa’iidzii(< /naa-í-iid-zii/) 'we two work’ -iid- + stem initial [l] → [tƚ] ex. haatƚee (< /ha-iid-lee/) ‘we two pull it out with a rope’ -iid- + other consonant → ø (zero) ex. hiiká (< /hi-iid-ká’/) ‘we two pound (a drum)’
The Jicarilla people have been in contact with Spanish-speaking and English-speaking peoples for a long time and have over time adopted loanwords that have influenced Jicarilla phonology. Most of the sounds used to take in a loanword from Spanish are sounds in Jicarilla. Some sounds not occurring in Jicarilla phonology are changed into Jicarilla as follows:
*Or /l/ as in "béela" (from ‘pera’ ‘pear’)
*Or /ʔ/ as in "ga’ée" (from ‘café’ ‘coffee’) *Or /k/ as in "kéesda" (from ‘fiesta’ ‘party’)
Words of Spanish origin using /p/ in Jicarilla are the only instances where the /p/ or any other labial obstruent did not descend from a sonorant.
"Báayoo" (from ‘paño’ ‘scarf’)
"Bíił" (from ‘automóvil’ ‘automobile’)
"Bołdóon" (from ‘bulto’ ‘small haystack’)
"Gołjóon" (from ‘colchón’ ‘mattress’)
