HAECCEITY

'Haecceity' (transliterated from the Latin ''haecceitas'') is a term from medieval philosophy first coined by Duns Scotus which denotes the discrete qualities, properties or characteristics of a thing which make it a ''particular'' thing. Haecceity is a person or object's "''thisness''".
Charles Peirce later used the term as a non-descriptive reference to an individual.

Haecceity and Quiddity

Haecceity may be defined in some dictionaries as simply the "essence" of a thing, or as a simple synonym for quiddity or hypokeimenon. However, such a definition deprives the term of its subtle distinctiveness and utility. Whereas haecceity refers to aspects of a thing which make it a ''particular'' thing, quiddity refers to the universal qualities of a thing, its "whatness", or the aspects of a thing which it may share with other things and by which it may form part of a genus of things. Duns Scotus makes the following distinction:
It is important to note that while terms such as haecceity, quiddity, noumenon and hypokeimenon all evoke the essence of a thing, they each have subtle differences and refer to different aspects of the thing's essence.
