[Lingtyp] Contact-induced grammaticalisation withOUT replication of existing constructions

[Pun Ho Lui]

Dear linguists,

I am wondering if anyone has reported any case of grammaticalisation emerged in code-switching.
The grammaticalised construction is not a replication of an existing construction in the code-switching languages because these languages do not have similar constructions. 

Thank you.

Warmest,
