Carrantuohill - Irish Place Names

Patrick Weston Joyce
1923

Carrantuohill, the highest mountain in Ireland. It descends on the Killarney side by a curved edge, which the spectator catches in profile, all jagged and serrated with great masses of rock projecting like teeth. Tuathail [thoohil] means left-handed, and is applied to anything reversed from its proper direction; carrán is a reaping hook; and Carrantuohill is "the reversed reaping hook," because the teeth are on a convex instead of a concave edge.
