Maya and created neologisms to express Catholic religious concepts. The result of this process of reducción was Maya reducido, a semantically transformed version of Yucatec Maya. Missionaries attempted to end Maya religious practices and destroy associated written works. By their translations, they also shaped a language that was used to convert, subjugate, and govern the Maya population of the Yucatán peninsula. But Maya speakers appropriated Maya reducido for their own purposes, resisting colonial domination. The oldest written records in Maya reducido (which used the Roman alphabet) were written by Maya notaries between 1557 and 1851. These works can now be found in the United States, Mexico, and Spain in libraries and archives. Phonology A characteristic feature of Yucatec Maya, like other Mayan languages, is the use of ejective consonants: . Often referred to as glottalized consonants, they are produced at the same place of oral articulation as their non-ejective stop counterparts: . However, the release of the lingual closure is preceded by a raising of the closed glottis to increase the air pressure in the space between the glottis and the point of closure, resulting in a release with a characteristic popping sound. The sounds are written using an apostrophe after the letter to distinguish them from the plain consonants (tʼàan "speech" vs. táan "forehead"). The apostrophes indicating the sounds were not common in written Maya until the 20th century but are now becoming more common. The Mayan b is also glottalized, an implosive , and is sometimes written bʼ, but that is becoming less common. Yucatec Maya is one of only three Mayan languages to have developed tone, the others being Uspantek and one dialect of Tzotzil. Yucatec distinguishes short vowels and long vowels, indicated by single versus double letters (ii ee aa oo uu), and between high- and low-tone long vowels. High-tone vowels begin on a high pitch and fall in phrase-final position but rise elsewhere, sometimes without much vowel length. It is indicated in writing by an acute accent (íi ée áa óo úu). Low-tone vowels begin on a low pitch and are sustained in length; they are sometimes indicated in writing by a grave accent (ìi èe àa òo ùu). Also, Yucatec has contrastive laryngealization (creaky voice) on long vowels, sometimes realized by means of a full intervocalic glottal stop and written as a long vowel with an apostrophe in the middle, as in the plural
