Two fundamental aspects of conceptual and linguistic structure are examined in relation to one another: organization into strata, each a baseline giving rise to the next by elaboration; and the conceptions of reality implicated at successive levels of English clause structure. A clause profiles an occurrence (event or state) and grounds it by assessing its epistemic status (location vis-à-vis reality). Three levels are distinguished in which different notions of reality correlate with particular structural features. In baseline clauses, grounded by "tense," the profiled occurrence belongs to baseline reality (the established history of occurrences). Basic clauses incorporate perspective (passive, progressive, and perfect), and since grounding includes the grammaticized modals, as well as negation, basic reality is more elaborate. A basic clause expresses a proposition, comprising the grounded structure and the epistemic status specified by basic grounding. At higher strata, propositions are themselves subject to epistemic assessment, in which conceptualizers negotiate their validity; propositions accepted as valid constitute propositional reality. Propositions are assessed through interactive grounding, in the form of questioning and polarity focusing, and by complementation, in which the matrix clause indicates the status of the complement.Languages 2019, 4, 22 2 of 20 ways conceivable. There has been a certain course of events, whereby certain events and situations have occurred, while countless others have not. Reality (R) is the history of occurrences, up through the present moment. This history cannot be changed; what has happened has happened. Reality is thus the established course of events. Future events are excluded from reality (so defined) because they have not yet occurred and thus have not been either established or fully determined. Moreover, our knowledge of reality is only partial and imperfect. Each of us has our own "take" on it, our own reality conception (RC). For a given conceptualizer (C), RC comprises what C accepts as real-i.e., as having occurred, or having been realized. This conception is always incomplete, and C is bound to be mistaken in many respects. But rightly or wrongly, RC is what C knows."Specific linguistic properties motivate the assignment of clauses to three main strata involving different levels of reality: baseline clauses and reality (e.g., Alice resembles her mother, Sam broke a cup); basic clauses and reality (she may have been followed, he didn't graduate on time); interactive clauses and propositional reality (he did graduate, have they left?). These will be considered in turn.
Baseline LevelThe description is based on Cognitive Grammar (Langacker 2008), which holds that grammar is inherently meaningful, residing in assemblies of symbolic structures (form-meaning pairings). For basic universal categories, like noun and verb, the framework posits both a schematic meaning, valid for all members, and a prototype corresponding to central members (Langacker 2015a). The pr...
