Aisling

The aisling (Irish for 'dream' / 'vision', pronounced [ˈaʃl̠ʲəɲ], approximately ASH-ling), or vision poem, is a mythopoeic poetic genre that developed during the late 17th and 18th centuries in Irish language poetry. The word may have a number of variations in pronunciation, but the is of the first syllable is always realised as a [ʃ] ("sh") sound. Many aisling poems are often still sung as traditional sean-nós songs.
