Lettermore, Irish language village in Connemara, Ireland

Lettermore is a Gaeltacht village on an island of the same name in County Galway, joined to the mainland by road. The island has two halves: the eastern half is Lettermore, the western half is Lettercallow (Leitir Calaidh). The name Leitir Móir means "great rough hillside".

Lettermore takes its name from the Irish Leitir Móir, meaning "great rough hillside". The island is divided in two: the eastern half is Lettermore proper, while the western half is Lettercallow (Leitir Calaidh), whose name refers to a rough hillside by a marshy area. The village lies within the Connacht province's County Galway Gaeltacht, and a 2002 census recorded 812 inhabitants.

The village's Irish name, Leitir Móir, means "great rough hillside", and Irish is the main spoken language of the area. Lettermore is part of the Gaeltacht, the districts of Ireland where Irish is the primary language and culture, so Irish appears on signs and is heard in everyday conversation.

The best way to visit is by car, as the islands are connected by bridges and causeways from the mainland. The layout is straightforward to navigate, with clear signs directing you through the island sections.

The individual islands each have their own Irish names, which locals use in daily conversation and reference. This naming system reflects how residents think about and relate to their divided yet connected home.
