What is in a gloss? Glosses are many kinds of attempts to supply what is perceived to be deficient in a reader's procedural or declarative knowledge.
According to Hullen (1989), glosses were once of three types: synonyms, encyclopedic comments, and grammatical notes.
Blohm (1982) coined the term gloss paraphrase, which he defined as "a type of reader-activated superimposed intratext notation that replaces abstractly-composed text content with concrete referents to promote readers' cognition".
