Primitive Irish was a language that people in Ireland used to speak a very, very long time ago. It was one of the first languages that people in Ireland ever spoke. This language was really important because it helped people in Ireland communicate with each other and understand each other.
When people spoke Primitive Irish, they used words and sounds that we might not understand now. They also used a different way of writing letters and words than we use today.
The people who spoke Primitive Irish had very different lives than we do now. They lived in a time when there were no cars or airplanes, no phones or computers. They had to travel by foot or by animals like horses. They had to grow their own food or hunt for it.
Some people still speak Irish today, but it is a different kind of Irish called Modern Irish. It has changed a lot from Primitive Irish over many years. So, Primitive Irish is kind of like a special treasure that helps us learn about the history of Ireland and how people used to talk a long, long time ago.
