Dear Sheila,

All the words you've specified are in the Irish language. Craic is pronounced like the English word 'crack', and means conversation, fun, chat, generally a good time. Seisiún is pronounced sort of like 'seh-shoon' in English, and means a social gathering. It is referred to mostly on this forum as a musical gathering. Sláinte is the Irish word for health, and is pronounced sort of like 'slahn-cheh' in English. It is used often as a toast, and also as a word of farewell.
