Coherence in linguistics is what makes a text semantically meaningful. Broadly conceived, linguistics is the scientific study of human language, and a linguist is someone who engages in this study. ... In the main, semantics (from the Greek semantikos, or significant meaning, derived from sema, sign) is the study of meaning, in some sense of that term. ...
Coherence should therefore be understood as a result of an interplay between textual and cognitive factors, where the text is assigned certain tasks and the reader other tasks.
Consequently, hyperstructural coherence is related to the textlinguistic notion of "global coherence", but since hypertexts have both a text level and a hypertext level, we will limit the application of the textlinguistic coherence categories to the level for which they are designed, which in our context corresponds to the node level.
Intranodal coherence can generally be strengthened on both local and global levels as each individual node can be made thematically homogenous, so that all subelements will have strong relevance both to their neighbouring elements and to the macropropositions at the top of the node.
