In this paper I list many examples of Nicobarese grammaticalization, explore grammaticalization paths, and attempt to reconstruct the proto-Nicobarese grammatical lexicon. Despite many superficial differences, I find strong underlying parallels between Car and Nancowry grammar, indicating that the extensive history of grammaticalization in Nicobarese is quite old, likely largely pre- or proto-Nicobarese in depth.
