Grammaticalisation: Unidirectional, non-reversable?
Today's pattern of ergative marking may be evidence of this latter
grammaticalisation process since ergatively-marked NPs never took over entirely.
'Delimiting Innovations in the Category of Adverbial Subordinators: Some Evidence from the
Grammaticalisation of Provided (That) in Early English'.
The
grammaticalisation of a postposition into a case marker can take centuries (cf.
The issues relating to definite reference are considered relevant in Northern Sotho because definiteness as a grammatical category is viewed as the
grammaticalisation of a semantic and pragmatic category of identifiability, which is available across languages (Lyons 1999).
The reason this evidence is important is that it is reasonable to expect that the
grammaticalisation of pragmatic conditions can happen to different degrees in different constructions (Levinson 2000:264, 266).
