This chapter discusses the expression of information structure in the three indigenous language families of the Caucasus with a focus on constituent order and particles. At the clause level, all three language families show a clear preference for SOV, are generally flexible, and also admit other orders. The major focus position is pre-verbal, but postverbal focus is also attested; adjacency to the verb is a violable constraint. At the phrasal level, there is a sharp difference between Northwest Caucasian, with its prenominal and postnominal modifiers alike, and Kartvelian and Nakh-Daghestanian languages, which employ postnominal modifiers only for emphasis, contrast, or focus. Languages from all three families make wide use of cleft and pseudo-cleft constructions that normally express constituent focus. Another commonality is the frequent use of enclitics and suffixes of different types for information-structuring purposes. Modal markers, interrogative markers, additive affixes, and markers with grammatical meaning are used as focus-sensitive particles and usually placed after the item they scope over or after the head of the phrase.
