cohesion

Cohesion is the set of grammatical and lexical mechanisms that create surface-level connections within and across sentences in a text, producing textual unity. Parameters: the filer classifies cohesion into five types — (1) reference (pronouns, demonstratives that point to other text elements), (2) ellipsis (omission of recoverable elements), (3) substitution (replacement of one element by a generic substitute), (4) conjunctive adverbials (however, therefore, next — signaling relations between clauses), and (5) lexical cohesion (repetition, synonymy, hyponymy, collocation). Cohesion is observable in the text itself, distinct from coherence which is the reader's mental reconstruction of meaning. The concept was formalized by Halliday and Hasan (1976) and persists through linguistic theory, discourse analysis methodology, and computational text analysis.
