===Demonstratives===
Demonstratives agree with their referent in number and, if singular, in gender; medial demonstratives also agree with the addressee, a typologically unusual type of [[allocutive agreement]].<ref>{{harvcoltxt|Souag|2014}}</ref> The pronominal demonstratives are as follows:
* 'this' (proximal): m. {{lang|siz|wa / waya}}, f. {{lang|siz|ta / taya}}, pl. {{transliteration|siz|wi / wiyya}}
* 'this/that' (medial, speaking to a man): m. {{lang|siz|wok}}, f. {{lang|siz|tok}}, pl. {{transliteration|siz|wiyyok}}
* 'this/that' (medial, speaking to a woman): m. {{lang|siz|wom}}, f. {{lang|siz|tom}}, pl. {{transliteration|siz|wiyyom}}
* 'this/that' (medial, speaking to a group): m. {{lang|siz|werwən}}, f. {{lang|siz|terwən}}, pl. {{transliteration|siz|wiyyerwən}}
* 'that' (distal): m. {{lang|siz|wih}}, f. {{lang|siz|tih}}, pl. {{lang|siz|widin}}

When a demonstrative modifies a noun phrase, it takes a prefix ''da-'' (''ta-'' for feminine singular). To form a [[Presentative (grammar)|presentative]] ('here is...'), it instead takes a prefix ''ɣ-''. Placeholders ('whatsit', 'whatchamacallit') use the singular distal forms plus ''-in'' ({{transliteration|siz|wihin}}, {{transliteration|siz|tihin}}).

Demonstrative adverbials are based on the same series minus referent agreement markers: proximal ''-a / -aya'', medial ''-ok / -om / -erwən'', distal ''-ih''. Locative adverbs ('here', 'there') prefix to these ''gd-'' (or approximate locative ''ss-''), while adverbs of manner ('like this', 'like that') prefix ''ams-''.
