Acesso em: 15 mar. 2023.e- 2237-2083http://repositorio.bc.ufg.br/handle/ri/22122This study describes the manifestation of the category of number in sign languages, aiming to identify the values, the main forms and strategies available and some intramodal and intermodal manifestation patterns, considering the noun phrase. To this end, we worked with a sample of 10 sign languages, from different regions and historical groups. Based on secondary data, we identified that some sign languages have optional number marking, which presupposes the presence of the general number, and that other sign languages have obligatory number marking. In sign languages where number marking is optional, the general form is similar to the singular form, expressed by zero. The values of the category of number are singular, plural and dual, expressed by syntactic and morphological strategies, but preference is given for the former. This preference suggests that sign languages are isolating languages with regard to the category of number, differing typologically from spoken languages in this respect. Furthermore, the number system in sign languages appears to be phonologically driven.porAcesso AbertoTipologia de línguas de sinaisUniversaisNúmeroPluralidadeSign language typologyUniversalsNumberPluralityArtigohttp://dx.doi.org/10.17851/2237-2083.30.4.1719-1751
