摘要：This paper discusses issues of the Morphology of LSB (Brazilian Sign Language) detailed in the internal structure of signs and the determinant rules for the constitution of these signs. Some studies on the morphological and lexical structure of sign languages found out LSB presents a considerable number of processes to form signs, among which are derivation, composition, numeral incorporation and negation incorporation. Considering Ferreira-Brito (1995), Quadros e Karnopp (2004) and Felipe (2006), this work describes the occurrence of such processes in signs of the variety of LIBRAS of Belém of Pará.
