The present name of this townland, Keenaght, is very likely a reformed analogy of the neighbouring barony of Keenaght, with scribal errors adding a t to the end of anglicisations of its name such as with Tonaght in the neighbouring parish of Ballynascreen, which actually derives from Tonach.[2] It is more reasonably suggested that Keenaght derives from the synonym Coanna with the adjectival suffix -ach added to it.[2] This derivation is supported by the majority of earlier recorded forms.[2]
