Last week, Contae an Chláir native Seosamh Mac Ionnrachtaigh asked if I would help create a map in Gaeilge for him. He graciously worked with me to supply the many Gaeilge place names that appear on this map and help me understand the language and the geography better. For instance, the name “Shannon” has many different manifestations in this map – a river, a town, an airport, and an estuary, and each one is slightly different – tSionainn, Sionainne, and Sionnain. Seosamh explained that in Gaeilge, when two nouns come together, the second noun is in the genitive case, and that the letter ‘T’ comes before a feminine noun starting with ‘S’ in most cases in Gaeilge.
