Hey kiddo! So, have you ever heard of Ireland? It's a country with lots of cool history and traditions. One of those traditions is something called "triads".
Triads are basically groups of three things that are related. For example, one triad could be "the three most important things in life are love, health, and happiness".
In Ireland, there are a lot of triads that talk about important things in their culture. Some triads talk about Irish heroes, like the "three greatest warriors of ancient Ireland". Others talk about important virtues, like "the three things that bring peace: a clear conscience, forgiveness, and love".
People in Ireland have been using triads to pass down their culture and wisdom for hundreds of years. You might even hear people reciting triads in Irish pubs or at cultural events!
So, that's basically what triads are in Ireland. Groups of three things that are important to their culture and history. Pretty cool, huh?
