An adjective has the type cardinal adjective
if it has a numeric value (apart from the value one all values of positive
integers). This criterion is necessary and sufficient.
Test:
Given X an adjective:
If X has numeric value (apart from the value one all values of positive
integers), then X has the type cardinal.
Examples:
- Les deux / vaches sont malades.
- Ils sont deux /.
There are constraints concerning the selection of the determiner:
only the definite article, the possessive determiner
or the demonstrative determiner
can precede the cardinal adjective in a noun phrase. We consider that, for cardinal adjective,
the features number and gender do not apply. The noun specified by a cardinal adjective has to realise the
number value plural.
Test:
Given Art an article, Det a determiner, indf indefinite value, N a noun, NP a noun phrase:
If NP (Art/ + X + N), or
NP (Det/ + X + N) fails,
then X is a cardinal adjective.
Examples:
- Les/Mes/Ces deux / vaches sont malades.
- *Des/de deux / vaches sont malades.
