A Northern Ireland condition whereby an individual involuntarily adds a range of colloquialisms to the end of a statement, often as a means of self reassurance, that the statement is true and trustworthy. Much like "isn't it?". The condition is named after the most common of these: "so it is".
The exact phrase alters depending on tense, changing "so it is" to "so it was" or maybe "so it will".
The phrase can also alter to reflect a person or a third party object: "so he was", "so she will" or "so it would"
There is also the negative: "so its not"
