[Ir. Cill Tartain, Tartan's Church].
River and barony in south-east Co. Galway, Ireland. Once the site of Coole Park (demolished 1941), the estate of Augusta, Lady Gregory (1852–1932), who used the name in titles of her collections of folklore, e.g. Kiltartan History Book (Dublin, 1909), The Kiltartan Wonder Book (Dublin, 1910), etc. ‘Kiltartan English’ or ‘Kiltartanese’ denote her attempts to record what she felt was the poetic diction of country people in the area; the phrases are sometimes used disparagingly today, implying a patronizing falsity.
