Morphosyntax Constructions of the World's Languages

Several kinds of relations between events often have distinct complex sentence constructions, in particular those involving degree, causation, factivity (epistemic stance), or a combination of these. Comparative and equative constructions compare degrees of a property predicated of two different referents. The strategy chosen depends on the strategy used for temporal complex sentences, at least for comparative constructions. Conditional constructions express a causal relation (content, epistemic, or speech act), but, unlike causal relations, also express a nonfactive (neutral or negative) epistemic stance toward the events. Past tense constructions are often recruited to express nonfactivity. Concessive constructions presuppose a causal relation that is unexpectedly violated; concessive conditional constructions are the nonfactive counterparts. Strategies use conjunctions recruited from conditionals or expressions of obstinacy, focus marking, and remarkable co-occurrence. Concessive conditionals use a scalar, alternative, or universal strategy to conceptualize the concessive conditional relation. Other relations, such as the comparative conditional, may also be conventionalized.
