A shift from the usage in medieval philosophy to the usage in analytic philosophy.

Medieval usage, Duns Scotus

haecceity is species, the essence of a kind
quiddity is particularity, the essence of an individual

Analytic metaphysics often separates:

objects
properties
relations

So the questions become:

What individuates **objects**? → haecceity
What individuates **properties**? → quiddity

Compare fungible, numerical identity
