"Haecceity (/h\u025Bk\u02C8si\u02D0\u026Ati, hi\u02D0k-/; from the Latin haecceitas, which translates as \"thisness\") is a term from medieval scholastic 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\", the individualising difference between the concept 'a man' and the concept 'Socrates' (a specific person)."@en .
