The position of the demonstratives is always postnominal, but the positon of the demonstratives in relation to a noun modified by an adjective is not straightforward. Roughly speaking, the distal si precedes the adjective whereas the proximal dhe follows it:
moto si ngai
[motorcycle DIST big]
'that big MOTO'
moto ngai dhe
[motorcycle big PROX]
'this big MOTO'
