* One theory is that it comes from the Irish word "teagach", meaning "a house". This word was often used to refer to Catholic churches, and so it is possible that "Taig" is a corruption of this word.
* Another theory is that it comes from the name of a Gaelic chieftain, Teague. This chieftain was known for his opposition to English rule, and so it is possible that his name came to be used as a derogatory term for all Catholics.
* A third theory is that it is simply a corruption of the word "Catholic".
Whatever its origin, the word "Taig" is now widely used as a derogatory term for Catholics in Northern Ireland. It is considered to be very offensive, and its use is likely to cause resentment and anger.
