What is "partitionism"

n. (context Ireland politics English) The treatment of Northern Ireland and the Republic of Ireland as distinct.

In Ireland, partitionism refers to views on Irish politics, culture, geography or history that treat Northern Ireland and the Republic of Ireland as distinct. Partitionists may emphasise the perceived differences between the two jurisdictions and the people who live within them.

It has mostly been used to describe those in the Republic of Ireland who view Northern Ireland and the people who live there as separate and different. It is usually used among Irish nationalists and republicans "as a criticism of those in the south who pay lip-service to the ideal of Irish unity but who are smugly comfortable with a 26 county republic".
