Intersective modifier

In linguistics, an intersective modifier is an expression which modifies another via set intersection. One example is the English adjective "blue", whose intersectivity can be seen in the fact that being a "blue pig" entails being both blue and a pig. By contrast, the English adjective "former" is non-intersective since a "former president" is neither former nor a president.
