5.1. Coherence and discourse markers
Coherence is that property of a text through which it is possible to organise and guarantee a logic transmission of meanings. In order to assure coherence, it is necessary that the conceptual building blocks of discourse follow a certain order and are united through logical connections as well as discourse markers. Two or more utterances can be linked to each other by discourse markers which involve conjunctions (LEXICON 3.9), reformulations, argumentative markers, and discourse particles.
As stated before, discourse markers can be explicit, namely overtly expressed, or implicit, namely left unexpressed. As will be discussed in the following sections, overt particles in LIS can be realised throughout manual signs, non-manual markers, and spatial relationships.
