Editing Yucatec Maya language (section)

===Acquisition===
Phonology acquisition is received idiosyncratically. If a child seems to have severe difficulties with affricates and sibilants, another might have no difficulties with them while having significant problems with sensitivity to semantic content, unlike the former child.<ref name="Straight, Henry Stephen 1976 207-18">Straight, Henry Stephen (1976) "The Acquisition of Maya Phonology Variation in Yucatec Child Language" in Garland Studies in American Indian Linguistics. pp.207–18</ref>

There seems to be no incremental development in phonology patterns. Monolingual children learning the language have shown acquisition of aspiration and deobstruentization but difficulty with sibilants and affricates, and other children show the reverse. Also, some children have been observed fronting palatoalveolars, others retract lamino-alveolars, and still others retract both.<ref name="Straight, Henry Stephen 1976 207-18"/>

Glottalization was not found to be any more difficult than aspiration. That is significant with the Yucatec Mayan use of ejectives. Glottal constriction is high in the developmental hierarchy, and features like [fricative], [apical], or [fortis] are found to be later acquired.<ref name="Straight, Henry Stephen 1976">Straight, Henry Stephen 1976</ref>
