Where do complementizers come from and how did they come about?

Abstract

Abstract It is an old and widespread assumption in historical linguistics that hypotactic structures evolved out from paratactic structures. In more recent times, the parataxis-to-hypotaxis hypothesis was associated with the assumption that syntactic structures are discourse-based. This means that hypotactic structures evolved via syntacticization, i.e., via “a process by which flat, paratactic discourse-pragmatic structures transform over time into tight, hierarchic syntactic structures” (Givón 1979: 82f.). One special aspect of this assumption is that complementizers are held to have grammaticalized from nouns, verbs, prepositions, or pronouns in bi-sentential, paratactic source structures. In this paper, I will re-evaluate the existing evidence for the parataxis-to-hypotaxis hypothesis with special focus on the emergence of complementizers. The result of the re-evaluation is that in all cases, where we have enough historical data to reconstruct the development in detail, we have to assume a source structure that already displays subordination. In most cases, the subordinate clause is a relative clause suggesting that relativization is probably the oldest form of subordination. The over-all result of the re-evaluation is that there is no reliable evidence at all for the parataxis-to-hypotaxis hypothesis in its current form.
