Functor

Functor is a notion which DiSciullo & Williams adopt from Categorial Grammar to express relationships between entities.

Example

if one wishes to express the idea that y is the sister of x, the property 'sister of' can be formalized by using a functor, say F, and write 'y=F(x)'. See Function composition.
