A language uses the same forms for both pronominal demonstratives, which replace noun phrases, and adnominal noun phrases, which accompany referent nouns.  In the English constructions "I love <i>this</i>" and "<i>This</i> shoe doesn't fit," the same form of the demonstrative <i>this</i> acts first as a pronominal, then as an adnominal.
