Many people who speak Irish can understand some Irish corned beef stew Gaelic but not Welsh because the Celtic languages are divided into two groups.
One group is called the p-Celtic languages, and the other is called the q-Celtic languages. Irish and Scottish Gaelic are q-Celtic languages, and Welsh is a p-Celtic language. Irish has no “yes” or “no” words. There were great poets who wrote in Irish.
