A grammatical framework that models sentence grammar and discourse-organizing expressions as interacting but distinct domains of linguistic organization.

Core Idea

This is the specific framework associated with a two-domain distinction, not the generic grammar of connected discourse; classifications of parentheticals and discourse markers remain theory-dependent. Utterance material is assigned either to sentence grammar, which builds propositional clause structure, or to thetical grammar, which organizes parenthetical, interactional and discourse-management units; their combination accounts for linear discourse. The abstraction is therefore identified by a declared carrier, a transformation or constraint over that carrier, and an invariant that tells an analyst whether the named structure is genuinely present.

Scope of Application

Discourse grammar belongs to linguistic theory and is useful where the analyst can specify the typed linguistic theory carrier, including objects, relations, parameters, conventions, evidence, boundaries, and comparison targets, then evaluate the spoken or written discourse, sentence-grammar and thetical-grammar domains, propositional clause structure, parenthetical or extra-clausal units, discourse markers and formulae, syntactic integration and prosodic separation, linear placement, cooptation or grammaticalization pathway, interface rules and evidence distinguishing the domains are explicit.

Clarity

The abstraction clarifies a crowded vocabulary by making the spoken or written discourse, sentence-grammar and thetical-grammar domains, propositional clause structure, parenthetical or extra-clausal units, discourse markers and formulae, syntactic integration and prosodic separation, linear placement, cooptation or grammaticalization pathway, interface rules and evidence distinguishing the domains are explicit the center of the account. A claim should name the carrier, the governing operation or relation, the applicable assumptions, and the recognition test.

Manages Complexity

Without the abstraction, an analyst must reason directly over many local details: the carrier roles, admissibility assumptions, competing conventions, derived invariants, boundary cases, and proof or validation obligations specific to Discourse grammar. Discourse grammar compresses them into the roles in the structural signature. That compression permits comparison across instances without erasing the variables that determine validity. It also exposes which details may be varied safely and which are constitutive.

Abstract Reasoning

  1. Identify the carrier. State what the elements, states, objects, or observations are: the typed linguistic theory carrier, including objects, relations, parameters, conventions, evidence, boundaries, and comparison targets. Reject examples whose alleged carrier belongs to a different problem. 2. Lock the constitutive rule. Express the spoken or written discourse, sentence-grammar and thetical-grammar domains, propositional clause structure, parenthetical or extra-clausal units, discourse markers and formulae, syntactic integration and prosodic separation, linear placement, cooptation or grammaticalization pathway, interface rules and evidence distinguishing the domains are explicit independently of one notation or implementation.

Knowledge Transfer

Knowledge transfers strongly among subfields of linguistic theory because they reuse the typed linguistic theory carrier, including objects, relations, parameters, conventions, evidence, boundaries, and comparison targets, Utterance material is assigned either to sentence grammar, which builds propositional clause structure, or to thetical grammar, which organizes parenthetical, interactional and discourse-management units; their combination accounts for linear discourse., and type the carrier, state every parameter and convention in the definition, test that the spoken or written discourse, sentence-grammar and thetical-grammar domains, propositional clause structure, parenthetical or extra-clausal units, discourse markers and formulae, syntactic integration and prosodic separation, linear placement, cooptation or grammaticalization pathway, interface rules and evidence distinguishing the domains are explicit, compare the nearest accepted identity, and report counterexamples, uncertainty, and limiting cases.

Neighborhood in Abstraction Space

Discourse grammar sits in a crowded region of the domain-specific corpus (11th percentile for distinctiveness): several abstractions share nearly its structure, so a description that fits it tends to fit its neighbors too.
