A language's pronominal demonstratives, which replace noun phrases, have different stems than adnominal demonstratives, which accompany referent nouns.  For instance, the French demonstratives <i>celui</i> and <i>celle</i> act pronominally, while <i>ce</i> and <i>cette</i> appear with nouns.  Consider the sentence <i>Donne-moi <b>ce</b> livre-là et garde <b>celui</b>-ci pour toi</i> 'give-me <b>this</b> book-there and keep <b>this</b>.one-here for you," which translates as "Give me that book and keep this one for you."
