Table 1 Representation of diachronic scenarios underlying the interaction between case and word order.

From: The evolutionary dynamics of how languages signal who does what to whom

Diachronic scenario

Description

Hypothesis

verb-final WO → case

verb-final word order causes case

processing hypothesis, noisy channel hypothesis, and word order universal

flexible WO → case

flexible word order causes case

trade-off hypothesis, corpus studies results

absent case → absent flexible WO

absent case causes absent flexible word order (i.e. leads to rigid word order)

a theory of licensing and structural case, corpus studies results

case → flexible WO

case causes flexible word order

trade-off hypothesis vs a theory of licensing and structural case and corpus studies results
