This paper aims to systematize the verbal negation in Portuguese Sign Language (LGP). From the lack of structured information about LGP’s Grammar and linguistic behavior comes out the necessity to study this language in a more detailed way, namely the subject matter. To oppose to this lack linguistic description, the present research gives an analysis and characterization of the structure and formation of verbal negation in LGP, based on video-recorded interviews, with informal incited speech, and video documentary with LGP deaf signers. The formation of negative sentences in LGP are compared with the same negative constructions from other sign languages in an attempt to verify similarities and differences between sign languages. It will be made known a group of negative markers (manual and non-manual) that contribute to the formation of the negation in LGP as well as a suggestion of segmentation in two main pillars: the regular form of negation (synchronic, asynchronous and past, present and future inflexion) and the irregular negative form. It will be shown the reason why we can assume the non-manual marker “headshake” is grammatical.
