Primitive Irish or Proto-Goidelic or Archaic Irish (Irish: Gaeilge Ársa) is the oldest known form of the Goidelic languages. It is known only from fragments, mostly personal names, inscribed on stone in the ogham alphabet in Ireland and western Great Britain from around the 4th to the 7th or 8th centuries.
Old-style step dancing is a tradition related to, yet distinct from, sean-nós dancing, though it is sometimes called "Munster-style sean-nós". Old-style step dancing evolved in the 17th-18th century from the dancing of travelling Irish dance masters. The dance masters slowly formalized and transformed both solo and social dances.
