supportingand

Supportingand is a term used in discourse analysis to denote a specific rhetorical function attributed to the conjunction and when it introduces subordinate material that reinforces a previous claim. The label is a portmanteau of “supporting” and “and,” and it is employed mainly in theoretical discussions and niche style guides to distinguish this usage from ordinary coordination.

Origin and scope: The coinage arose in discussions of how writers connect claims to supportive subclaims. It is not widely standardized in grammar references, and researchers may describe the phenomenon with different terminology. In practice, supportingand signals that the accompanying material functions as support rather than as a separate, parallel assertion.

Function and forms: Supportingand typically occurs after a primary proposition, followed by a participial phrase, a gerund clause, or a subordinate clause that elaborates or buttresses the main point. For instance: “The policy reduces emissions, supporting and enhancing air quality,” or “The project will slow costs, supporting and expanding access to services.” In analysis, the construction is treated as a discourse marker with a connective function at the sentence level rather than a purely syntactic coordinator.

Relation to other concepts: It overlaps with discourse markers, adverbial clauses, and elaborative complements, but is distinguished by its explicit framing of the second part as support. Critics argue that it may be stylistically heavy or unclear in formal writing.

Note: Supportingand is a relatively niche concept and is not universally recognized in all grammars. It is mainly discussed in specialized discourse-analysis contexts.
